can a 2.3 cylinder head be shaved and if so how much

 

[Stinger]

Yes, they can be shaved.

We'll need to know your setup, what fuel you want to run, etc. before we say how much...

The head can physically be shaved until you just barely touch the bottom of the intake bolts. Of course, that would give you something around 12:1 with flat tops. A more reasonable number to shoot for would be around 9.8-10:1 for pump gas. I ran 10:1 on pump gas, and was still able to run plenty of timing.
