Need help on buying heads!!!!
Need help on buying heads!!!! Okay this is my first post. I am currently interested in buying heads from a user on this sit these are the heads.
- Absolute Speed stg 2.5 5.3 heads
The chamber size is 58cc(milled.030), valve size (Manley Valves) 2.05, 1.57, Springs are Comp 977s with titanium retainers.
I spoke to the seller and he said with stock head gaskets the Scr would be about 11.4. So my question is would the compression be to high for my motor.I have a 98 camaro with a 2000 motor with 20k on it the motor is bone stock and has only kooks headers I have a lunati cam that I will be putting in the specs are 216-221 duration and 580 lift int and exh thanks in advance Pete

I run TEA 5.3 heads milled .030 with 58 CC chambers with a .040 Cometic gasket and I beleive that my compression ratio is 11.4-11.5 to 1. I beleive that with a stock GM gasket your going to be looking at a little lower compression ratio than 11.4 to 1.
attached is a spread sheet with the compression formula in it i filled in your specs and with a stock gasket u will b lookin at 11.1 :1, with a .040 gasket ur getin closer to 11.5 :1 as stated take a look at the exel sheet should help u
ok so it wont let me upload the file but that should b the compression ratio your lookin at
