Alright. So... I'm still on the fence...

Here are my options... and all of them involve pulling the engine:
(Refresher - engine looks clean as of last pull, probably a .30 over already - rod knock noise now)

1. Find a machine shop which will just do the minimum repair (having trouble finding a shop that says they will just replace a broken part without "going through" for $2500)
2. Have a machine shop do a $2500 "go through" the engine (and do I pay the extra $400 for dyno w/tuning?)
3. Go thru engine & port my #16 heads
4. Go thru engine + do rotating assembly
5. Go thru engine + new heads, new intake.
...any other combo...


Also... how much of a cam have you been able to put in without losing manifold vacuum?
I have power breaks and a mild cam, 16PSI of vacuum at the intake.
