My car is an 1995 50 GT, stock bore, stock pistons, stock bottom end.. the motor has been freshened up and in the process it has been zero decked.
I am going with a 2.02/1.60 valve aluminum head. I know i have to fly cut the pistons because I have .035" PV clearance.. That was checked without a head gasket.. using an E cam and 1.6 RR's but I want to use 1.7 rr's
I am also trying to get to 10.5:1 compression ratio
Now by fly cutting my pistons, I am assuming that Its going to lower my compression by a large amount..
My questions are
how do i determine how many CC's this will add by fly cutting?
How deep can i fly cut the stock piston??
when i mill my heads to make up for the valve releifs i cut, wont this make me have to fly cut the exhaust valves as well and therefor just set me right back to where i was on compression before I milled the heads??
