318 - intake vacuum leaking

.100 on a small block mopar head? Wow.... .060 is the max I've know folks to go. Slant six head? yeah, done .120 on them..

I called my machine shop and he questioned that amount too. States he never cuts that much with out machining intake side also.
Maybe my number is off. The heads were done 2 years ago. Sucks to get old.

Make sure the china wall gasket is not jacking the intake up. see post #3 [/QUOTE said
Do you mean the crossover snap in steel plate? Sorry never heard it call the "china plate" before.
I do not not have those because the LD340 is solid- no cross over openings

Take the intake off. Clean everything up, and set the manifold on the motor with no gaskets. Test fitting. It's possible just the end gaskets are leaking.

"End Gaskets leaking?" I'm sucking oil out of the galley directly into the intake port. Not leaking oil.
I think the intake is sitting too high now with the machining of the cylinder head block surface being cut.

Basically I just wanted to use a thicker gasket but realizing now a thinner gasket or more machining needs to be done.
I hate to cut intake but easier than pulling heads. Okay - i will stop crying. I sound like a newbee when I've been doing this for over 35 years. Just getting old.
