How much compression

My head is milled .030 and I run a 40 shot every now and then when at the track. Would 13.5:1 pistons be ok to run?

No I wouldn't, I mean street riding would it be ok with that compression and 93 octane?

13.5:1 pistons + .030 off the head could lead to CR = 15:1???
that would be pushing pump gas a bit...

I think you would be ok without the spray depends on what is the highest octane available in your area. 93 would be the lowest I would run. And I agree with Smokin I would stick to the good stuff on the spray. You running stock valve springs?

He doesn't have 13.5 pistons .. He has stock pistons with the head milled 30 .. No where near 15.1 .. Closer to 13.1

P/S entropy i hope you are feeling better and getting back in to shape ..

smokin',
i am slowly getiing back to normal, it's gonna be a long haul... You know what a long haul is i'm sure.

I took his note to mean that hehas milled .030 off the head and is now looking at installing pistons designed to give 13.5:1 (with stock head)
