Good am FGF. My mechanic is trying ot install my new engine (made by "Tuff Dawgs"). The driver's side is touching the stock brake booster as he lowers the engine. Because of the size of the rocker arm, my valve cover has to be a little higher than the stock one. Have you guys encountered this problem before? What is the correct procedure for this? I told them to remove the valve cover, install the engine and reinstall the valve cover. Or, remove the brake booster, install the engine, and reinstall the brake booster. Any help is appreciated. Thanks.

I would take valve cover off. Brake booster more trouble.

Thanks Gus. That is what I will have them do first.

I'm thinking if the brake booster is causing interferring issues with tall valve covers - what about the wiper motor?

Did he try to tilt the rear and/or LH side down while lowering?
How tall are the covers? Some wont clear the factory size booster.
May have to get a smaller "tandem" one.

Not sure if he tried to tilt it but he removed the booster. This was more than an hour ago and he has not called me yet, which is a good sign.

Send us pic if you can. I can't image why he has to remove the brake booster. Does he still have the RAD in? Sounds like it's crowded. Do you have A/C?

I had the same problem, the tall valve covers will not clear the 12 inch booster. So I got rid of the power booster.

So how do I upload pictures in this forum?

What motor is he putting in, Pontiac or Chevy?

It's a Pontiac 350 with some performance parts in it.

I am trying to post a picture of my valve cover and brake booster hitting each other during install. Here it is.

Ok. Figured how to post pics. This is a picture of my Pontiac 350 with a tall valve cover hitting the brake booster during installation. Engine still needs to shift towards the booster to install mounting bolt to the engine mount.

As Region Warrior said earlier, you simply need to replace that factory booster with one of a smaller diameter if you intend to use those valve covers. This is typical for FGF's with tall valve covers on the engine.

Do I have to use the tall valve covers? Obviously, the engine manufacturer used the tall ones for a reason (biger rocker arms). But If I find a lower profile valve cover and it does not touch the rocker arms, would it be alright? The only compromise would be the air space between the rocker arm and the inside wall of the valve cover will be less (less space for the oil to splash around), is this compromise pose an issue with performance and function? If I can get away with changing the valve cover rather than the booster, cost will be less.

Shouldn't need tall covers unless using either shaft rockers or a stud girdle.

Definitely get some stock height valve covers and you should be fine. If you are running adjustable rocker arm nuts(poli-locs), some are taller than others and you might have to run two valve cover gaskets stacked on each side but that should do it. You can go as short as your rocker arms will allow without hitting.

Ok. Thanks To all. I will try to acquire a lower profile valve covers.

One note if you running roller rocker sometimes the stock valve covers are not tall enough for a stock gasket. SD performance sold me a thicker gaskets to compensate.

I ended up installing lower profile valve covers. Works great. Inside clearance measures around 1/2 inch. I've attached a pictures. This engine came from Tuff Dawgs by the way.

Looks great!
