Do I need different heads for ATI blower? I currently have MTI stage II heads, milled .030". I just ordered an ATI supercharger, and I want to lower my compression. Will changing the gaskets, pistons, rods, bearing, etc. be enough? Or, do I have to buy new heads?
You're at 10.4:1 - 10.5:1 now with the milling.
You can get by with that compression, but when you tune the car you might dialing back the timing a bit more than if you had stock 10.1:1 compression.
In an ideal world you would someday get some 70cc 6.0 heads and drop the compression down to 9.8:1 or less.

The 6.0L heads, good tune, and YOU MUST HAVE AN INTERCOOLER....to try 10psi w/out an intercooler ur just a time bomb waiting to happen...bad batch of gas...ur buying a new shortblock. U could sell ur MTI heads for a set of ported 6.0L heads...just make sure they haven't been milled.
