I am trying to get a g23 together and I just need to get the pistons to put it together. I want to get custom light wieght ones that give me a high compression ratio and wont have clearance issues. I plan on useing type s cams so nothing too aggressive. How do I figure out how much positive dome I can run? I dont want to order them and then they dont work. I have the f23 with h22 head running e85

That doesn't tell me if it fits, just compression

when you asked how much dome you could run i assumed you meant compression. my bad.

so you're wondering about dome clearance with the chamber and/or valves? i could be wrong, but i'm pretty sure you'd be kissing valves before you hit the head. the only way to check this clearance would be to 'clay' it once it's assembled... but generally any OE honda piston or aftermarket piston made for Honda application should fit without contacting the head (if the compression height is right)

I want more than 12.5:1 if it will work

You won't be able to run E85

Um yeah I can and will need to with the comp. I want
