compression test results.
I figure compression with these heads and a standard FelPro gasket (.039" thickness) is 7.95:1 at best. That explanes why the car has always been pretty soggy down low.
The Magnum heads and a thinner .025 gasket should put me at 9:1 wich would wake it up by itself. The trick is going to be picking the right cam so I'm not bleading off any of the pressure. I'd like to use a moderately sized solid cam. I was looking at the CompCams Magnum 296 wich is 246 @.050" but that may be a bit large.
