Can head chambers be enlarged? I was just curious if the chamber on heads can be enlarged. I have a set of 65cc heads and I'd like to have them at 72cc. I have quite a bit of money and work invested in these and would like to hang on to them if possible.

It would be too easy to get into the water jacket IMO. Not sure if there is a common casting for the internal passages in the heads or not. If so, you may be able to have the chambers on a LQ4 head digitized and have that chamber cut to that profile.
It would be much cheaper to sell you heads and get what you want, or to have ordered a dished piston (Assuming this is for the 408 in your sig.)

After checking I would need something around a -30cc dish or more to get my compression low enough. Do I have many piston options? Is it a good idea to have that much dish with boost?

Honestly I know you have money tied up in these heads, but for boost head porting isn't as critical as it is for N/A. I really think you would be better off selling your heads and getting some truck LQ4/LQ9 heads that already have 71cc chambers orif it's in your budget a set of the new L92 heads and L76 intake.
