302 heads and cracking

The [email protected] duration on that summit cam pencils out to need about 9.7 compression ratio, same as 264 @.006
problem is it has no lift or area under the curve
what did you figure your compression is now that you have your heads?
did you post your deck clerance etc?
if you do have around 9.7 true CR check out a 264 lunati or Howards
if not post back
you can get a fatter lobe down to 256 if your compression is lower like 9:1
