would 671 heads work on a 455 any one know Thanks

Work? Yes. Best choice? No.

i have a problem vikki i have a set of 66 heads 670 heads and 671 heads i do not want to buy anymore heads.i have been ripped off for motors and other things so i do not trust to many people any more.so im trying to do the best with what i have.im still looking for a set of 96 but i have to get rid of all these parts and motors.You have givin me advise before and you seem to be one of the people that know what they are talking about. so any ideas would be nice Thanks

Ideally you'd want 90-95 cc heads. Your 670s and 671s are 72 cc, the 66 are 114.

Using the 670 or 671 heads would raise the compression impossibly high for a close to stock engine. You'd be at about 11:1.

On the other hand, the 66s are econo emissions heads, less than 8:1.

do you know some one with a set of 96 heads done.at a resonable price .also i have all these heads for sale 670 671 and 66 i was bidding on a set for 520.00 on ebay and missed them.they where complete and ready to go just bolt on.Ps somone you can trust..

96, 7K3 would be great choices. Big intake and exhaust.

1974 4X, 4C would be next as would 1975 5C, 6S. Big intake, small exhaust.

Some of the later 6X heads would work well, they vary in chamber size by codes so you'd have to know exactly what you were getting.

If it's to be a street engine, bolt on the 66s for now if they are in good shape. It'll run on low octane fuel and the 455 will still feel pretty good if you don't overcam it.

Those 96s Banshee had for sale were very good heads.

I can set you up with a set of heads at cost, if you are not picky with numbers I can see if I can find just the right ones for you. My machinist has some in stock and as I just had an engine done I can get a good price. He deals cash up front only.

did u get my post before this one

Yes. Re-read my last post.

6x-4's and 6x-8's work good.
Still plenty around at a reasonable price.
6x-8's could use a shave for more c.r.

banshees heads are complete ready to go,the 96 s sound good cash ok but i would send you the money if thats ok for your machinest.

I do not know if Banshee still has those heads or not.

My machinist does not have any of the "popular" casting numbers, just good heads. If you want a good set of street heads, they are a good choice.

thanks ponshoshop

ok i would perfer the 96 s if possible Thanks

I still have them...Sent you my address.

671 heads? Neer heard of them...

I have a set of 671s in my garage on a '67 400 2bbl. Not bird heads, they are big car only.

banshee are these heads complete ready to bolt on.I also sent you a pm asking this question. i also asked for a total with the brackets and shipping.checked my pm i do not see it.Thanks

We have been over the topic on the heads 3 or 4 seperate times over the past 3 months. You also have asked the same questions regarding the condition of the heads as many times and I have responded promptly. Again, the heads are complete but will need a rebuild. For $350, you will not find a servicable set of heads "ready to bolt on". You may, but they are few and far between.

I have been holding onto these heads for 3 months now after you told me you wanted them. I boxed them up and you told me you were sending the money.

To refresh your memory...

$350 for 96's is a pretty good deal.

I'd take the 670 heads but shipping would be horrendous.

I have an extra set of 6X heads that I would part with. They are originals off a 79 TA. They are the best version of 6xers. Perfect for use on a 455. They were rebuilt and then ran for approximately 500 miles. Ready to bolt on heads for $350 if you are interested.
I'll be happy to post pictures.

I'd have to pass on them based on the additude factor that comes with them.

I hope you are not talking about me and my 6x's. These are friendly heads with a happy happy seller.
And I will bend over backwards to please... Just call me Limbo Jimbo LOL

Attitude?

Will said he was sending the money, I wrapped them up and stuck his name on the FedEx lables. I offered to ship from Canada and save him $70. I have offered him good heads with no inflated shipping.

He said he was sending a MO and I have told 3 other buyers they were sold...tell me if you wouldn't have an attitude. But hey, one man's word is another man's business.

I am not mad at all...Just that when you spend 30 minutes boxing and labeling and passing up money from three others with the promise from another that money is on the way, one would be a little miffed.

The 6X's I have are 6X 4's. They are 92 cc's. Large valves with screw in studs. On a 455 they could give you around 9.6-10 to one compression depending on the pistons you are using. They really are the best thing going for a 455 for street use. These babies barely have carbon build up since the rebuild. Nice heads that were the originals on my 79 TA. They were only available on the highest performance 79 TA's. Great heads for only $350.

additude Did you mean attitude, graditude, altitude, that a turd... what?

Maybe, additurd?

Hmm, that must be a $hitty disposition. LOL

One good turd deserves another.... gotta stop!

Yep, I'm off to the KLR forum.

i have a set of 7k3 heads for 200.00 they will need to be redone and are complete

The 7k3 should be around 96 cc's. That would give you slightly less compression. Depends on what you want and what you want to spend. Probably going to cost more than the $350 I want for my 'done' ones just to get those redone.

yeah,buy jims.he needs the money

It would be best to buy what you need.

clicked on link banshee nothing there to refresh my memory.
im sorry you were in a rush im trying to get the best deal for my dollar.last email i sent i asked you for a total for heads and bracketts pullys and shipping.i do not rememer a total coming back to me pm.anyway if you want to give me a total its up to you. if not i will keep looking Thanks

Here are the pictures you requested. Email me at restorium@aol.com.







Please excuse the saw dust. They have been off the car and on the bench for about 18 months.

Those heads are red. They won't fit a Pontiac.

Sent PM with all the details from last conversation.

Not in a rush at all. Seen you looking for heads after you said you wanted mine and were sending money order. Was trying to offer you what you needed.

well right now with canadian dollar at par its the best time for me to buy.will send pm

jim,vikki said 7k3 heads were what was best for his motor.obviosly you know different.it dont matter to me.

It's all in your choices. And it depends on your budget. There's not a lot of difference between these heads, 6X, 7K3 or the ones mentioned earlier. The 6X would give you a few more HP just because of the chambers(slightly smaller). The biggest difference is that some need a rebuild and some do not. They are all great heads.
