OK, so with the flat tops, and .040 quench, it works out to like 10.26:1, is that too much for this motor??, If I use a thicker gasket wouldnt that lower it back down to a more reasonable level?

Volvo uses an aluminum 4 bbl intake with a brass water jacket on their carbed Vortec 5.7 engines. Even the 2bbl version. They use an adapter to put the 2bbl carb on it. This intake looks just like an Edelbrock Performer. It has the carb mounting that will take a spread bore or square bore carb. I have one I'll sell for $150 plus shipping if anyone wants it.

My notes indicate that Merc's #7561 head gasket is GM's #14096405 and has a compressed thickness of 0.028", which should give you about 9.9
Felpro's 17030 head gasket has a compressed thickness of 0.039, which should give you about 9.7
Sorry to throw another wrinkle at you, but for 9.9 or 10.26, I think you better check the Dynamic Compression Ratio.
