aluminum intake installation - 05/20/08 12:25 PM
This is my 1st attempt at rebuilding an engine.
I have a 440 with new Edelbrock Alum. heads and Performer manifold. When trying to install the manifold, the bolts will not go in straight. If I don't use the gaskets, I can bolt everything together, but, with gaskets, the bolts will not thread. I heard from some folks that I should discard the gaskets and RTV it only. Has anyone had this problem. The block has not been decked and the heads, valley pan, and intake are new.

Who made the gasket? I have had big problems with
Mopar Performance gaskets. They are crap. Nothing
but problems for me. Others may have had luck.
Mr Gasket makes a nice one, and Felpro also.
My 2 cents is stay away from the silicone and use
a good quality gasket.

hi
use the valley pan only with a SMALL bead of sylicone around all ports and bolt holes an a dab in each corner where the heads and block meet!
running between bolt holes and ports also .

Not that it matters, but if you read the service manual they tell you absolutely do not use sealant
except for where the side gaskets meet the valley
gaskets. Mr. Gasket has a nice bead of silicone pre
formed around everything on the sides, Fel-Pro gaskets have a formed rib around everything that crushes. Just my .02$

I've never used the gaskets, just the tin with a dab of copper or black rtv in the corners.

It should go in with just the metal pan and great stuff in the corners.
I know you said that YOU did not mill the heads, block, or intake, but it sounds like some milling on something was done in the past to give you the problems you are experienceing. You may want to have a few thousandths shaved off of the intake to make it fit well because you may get her to bolt on to the motor okay, but it doesn't need to be off much to suck oil into the intake runners and give you a vacum leak...I know this from past experience BTW.

Hi,
Yea I think most guys run into this problem! You can run it without gaskets and use RTV but I would rather not. I dont like RTV around the intake ports because if you read about it,it breaks down when exposed to fuel. I have done it without problem but instead I use the RIGHT STUFF they sell it at Napa-works awesome. Another thing is theres a guy on ebay selling really thin (I think .018 thick gaskets)compared to .045 (If I remember)Mopar performance and Felpro thick gaskets.-Gary
