i am looking to do this same thing in pretty much the same car, but i was wondering if you knew what the compression was if you left the phase II pistons in and just ran stock 2.2 heads.
There is one post that contradicts it's self a little bit on CR
In N/A form this set up bumps up the comp ratio to about 10:8:1 with the Phase II pistons(valve cut outs) the ratio is in the high 11's.I wanted to be safe so went for the dished Phase I pistons.
or are you saying with the phase I pistons in the phase II block gets you a CR of 10.8:1 and the phase II one would be in the high 11s.
So did you have to do any work to the pistons so the valves wouldn't hit them?
What rods did you use? Or are they both the same?
what is a delta grind?
Sorry about all the questions, but it's good to find some one that did the same thing that I am trying to do.
