having to bore out to 81.5 and was wondering which was the better route to go. with the 9:1 and the 9:2:1 i could go with cometic head gasket. give input. any will be helpful!!!

 

what are your plans for the engine? boost or N/A?

 

hmm with 9:1 or 9.2:1 i think that is a leaning towards boost since he isnt raising his compression. thats my 2 cents

 

all natural

 

YOu definately would want more compression if you wanna do all motor. At least get it to 10 ish, if not even higher.

 

hmm mayb 11:1 is good.

 

ok so 10:5:1 but should i go srp or cp pistons? srp are a little cheaper but i didnt know if there was much of a difference since both are same compression ratio. is it worth it to go cp instead srp?

 

CP over SRP for sure.

 

cp pistons are one of the most accurately made pistons, they are always the exact bore they are suppose to be.
