Would there be any benefit in a set of 2.02 camel humps cut from 64cc to 60cc?And would any body know what kind of compression might I be looking at with forged flat tops and these haeds?Thanks

Depending on your quench, you'll go from 10:1 to 10.46:1. What cam?

Here it is. Its a crane cam part#110692
Lift-502 intake 516 exhaust
Timing@.0040 tappet lift
Intake opens 41 BTDC closes 73 ABDC adv dur 294
Exhaust opens BBDC closes 44 ATDC adv dur 300
Cam timing @.50 intake opens 17 BTDC closes 41 ABDC
exhaust opens 52 BBDC closes 12 ATDC
max lift intake 102 ATDC exhaust 110 BTDC
duration @.050 intake 238 exhaust 244.

I suspect you will need that and maybe a schosh more compression with that intake closing point unless you advance it some if you can?

As always, jmho..
