Edelbrock heads...Am I crazy?

Aerohead cylinder heads good stock replacement I've had them on my car for 3 years no problems cheap too.

You weren't' kidding….$400 for the pair is a great deal.

I think these are the way to go for my budget and goals…I see they have an option for larger valves for $50…should I do it? what kind of performance change would that give?

Hardened seats are $80. I plan on driving the car under 100 miles a week. Is it a good idea to spring for that as well?


Using the KB 167 flat top pistons gives a piston head volume of +5cc. Plugging in the following numbers into the KB calculator I get a CR of roughly 8:1. What am I doing wrong here?

Cylinder head volume: 69 (arrowhead says 67-70)
piston head volume: 5.0
gasket thickness: .039
Gasket bore: 3.92
Cylinder bore: 3.91
Deck Clearance: .06
Stroke: 3.31

Obviously I want more compression than that…my goal was 9.5 to 9.8:1
