opening up 6.0 heads to lower comp. even more??

Has anyone done this? I was wondering if this was a good idea to maybe get the comp down to 9.3:1 or so.

The safest 317, aka 6.0L, heads can be opened up to is 74cc.

Like ls1290 said... I would only go maybe 74cc total. Just polishing the hell out of the CC will accomplish that... My #317 heads are 74cc's. Should get you pretty close to that 9.3:1 you're looking for.
