Sorry man.

Yes. Compression test, check spark plugs for oil and excess fuel, ect. Triple check your manifold to head gasket for vacuum leaks. Those can be sneaky little critters!

compression test done. #1-6. 100/115/115/105/120/110. i used water on the manifold gasket area and found that my idle drops when i pour it on heavy. i tried tightening the bolts and it didn't seem to help a whole lot. weird because the gasket is fairly new because of the recent build. sparks plugs were pretty dark but that would make sense due to running super rich.

You need to fix this vacuum leak. I got an old BBD that is pulling 20"


Could the bolts you are using too long?
They might bottom out and you would think they are tight. But they are not sealing the manifold.

svenster,

15" hg seems low for California. That puppy should pull 18-20 easy at sea level.

I'd still be looking for a leak.

ok. i feel like i should pull off the intake and have it planed. i have the clifford and the weird washer shim set up. planing would get both surface closer to matching and make sure that i have a level plane to work with. sound right? what intake gasket would be the best so that i won't have to remove the manifold again for the umpteenth time?

I use felpro gasket with no problems.
I use a thin layer of axle grease on the gasket so I can reuse it if I have to take it off again. This only works if the surface is even and you did not over torque the gasket.
It does make removing the gasket years later a cinch.

If you get the exhaust manifold done at the same time, you probably don't need a gasket for the exhaust.

If you have money to burn, take the head in also and have guide pins installed for both manifolds.

It could, how aggressive is that cam? What's the overlap?

A good torquey cam should still give you good vacuum.

head has guide pins for the intake, but not exhaust. rather not pull the head again due to the fact that i have the smaller head bolts and aligning the head to the block so that it didnt leak coolant was a real pita.

Make sure the alignment hole is deep enough when you have the surface planed.

If a cam has a lot overlap, the you will get lower vacuum. But You have little overlap but a good lift. Good cam.

Here is factory
