I think you'll need at least 12.5:1 static compression ratio to run that cam. All the good heads seem to be cast in 119cc chamber size, so it will take a pretty healthy lump on the piston crown to get you where you need to be. A 41cc dome should get you in the ballpark.

Most aluminum head manufacturers will recommend a certain composition gasket for use with their heads to prevent Brinelling. These gaskets will be in the neighborhood of 0.040".

I am totally dismayed at the advertising gimmicks of some manufacturers. In this episode, Edelbrock claims this cam makes power 1500 to 6500. BULL HOCKEY. Camshafts have a range of 3000 rpms in general and some may be effective in a 3500 rpm range. To say that this cam is effective in a 5000 rpm range is just not professional in my opinion. They're just trying to be everything to everybody. I'm seeing the cam as effective 3000 to 6500 at best and more like 3300 to 6300 if you want to get realistic.
