what would a piston with a .100 dome, stock head gaskets/valves/heads yield me as far as compression? i fear i may have used the wrong pistons

 

With a 3cc dome it put me at like 13.6:1. You need flat tops.

 

You need dome volume to calculate CR.

compression ratio aside, would i run into major piston to valve problems? or would i be ok if a made some valve reliefs in the pistons?

would any type of aftermarket head be any better? i really really dont want to tear the motor completely back down, that is an absolute last resort.

 

heads with larger volume will help (i.e. TF with 64cc?). with a sane cam, there will be no pv issues. is the block decked?

 

13.6 to 1 CR.

Kaboom.

 

...at least on any fuel less than 110 octane.

 

block is not decked.

so you think aftermarket heads with a larger combustion chamber would work with basically a le2 cam and my .100 domed pistons?

 

What is the dome volume?

im actually not sure..

there .030 forged probes. i havent been able to find the part number to find out

edit* - they advistise these pistons as producing a cr of 11.24 using 64cc heads if that helps
