MTI T1 cam is going in shortly. Heads are going to be started on next week (5.7L stock 99 castings), Stg 1.5 2.02 intake valves and stock exhaust valves. I was wanting to have the heads milled for more compression but was wanting some input...

How much should I mill the heads and what size head gasket should I run? Where does this put my quench at and how important is that?

Also, I believe the T1 is +4. Should I install it as such or install it where it doesn't have any advance?

I'm wanting the most power I can get out of this setup, but obviously I dont want PVC issues or horrible driveability. I just want to maximize this setup and this motor stuff is new to me, so any help is appreciated.

milling .020 and running a cometic .045 puts you at 10.96 SCR with a .037 quench assuming a stock -.008 deck height. with a .040 cometic its 11.10 SCR with a .032 quench, again assuming stock deck height.

yes the T1 is a 112lsa and 108icl, install it straight up, meaning the 108icl.

If you retard the cam you are going to move your powerband down a small bit.

I thought the stock deck height was -.005 ?

It varies from -.003 to -.010 (at least from info on this board). That's why everyone should always measure everything!

So how does this information factor into my quench and what should I be running (or what is the ideal range for a street car that seems the track a few times a year)? Personally I like the idea of milling less and then using a thinner gasket to obtain higher CR simply because if I need less CR in the future I can always switch to a thicker gasket, hard to add material to a head though. So for that cam, and 93 octane pump gas, what would be the ideal setup?
