Default milling the 317 6.0l heads? for 9.1compr. on a turbo eng.

hey anybody knows how much can i shave my 6.0 heads so i can lower the chamber cc so i can get them to around 65-66cc. Im using them for my turbocharged engine looking to be around 9.1 compression and what push rods will i need after i shave the heads?

Shouldnt be a whole lot but then again for that crap just look around for #241 or even better, #243 heads and you'll have a badass setup without milling anything. just my opinion tho, hope it helps some

measure for push rod length once you get your heads on.

I wouldn't deck the head's. You are going to need the deck thickness so you don't lift them and push water! IMO.

Yup I agree, I was gonna mill my L92's jsut a tad to dial in the exact CR I wanted instead of special ordering some slugs but why sacrifice clamping and screwing around with the quench, etc. Another thing is possible head lifting or just taking the heads of for god knows what reason. You'll need to mill/resurface them at this point and will make matters even more worse and end up having paper weights. Get the right or close to what pistons you want for the cc heads you'll be running. Those heads are great in FI so keep em.

100% agreed, you need that deck as think as possible, even unmilled there are not thick enough.
