Aluminum Heads vs R/T Heads

Yeah I agree I don't think the compression statement is true. But in my case that won't matter and I should have added that with an .035 headgasket and icon pistons I am at 11.2:1 compression right now with the R/T heads. The aluminum heads have a slightly small chamber and if I did the math right it puts me a little bit over 11.4:1.

@rumblefish360

The R/T heads:
60cc chamber
180cc rect. intake runner
2.02/1.625 valves

The eddy alumn heads:
58cc chamber
176cc rect intake runner
2.02/1.60 valves


If my lift is only at the .545 range I wonder if I will see any gain in hp. I was looking to make the car slightly faster (Gain 2 tenths of a second in the 1/8th) with the aluminum heads but I'm not sure if I will see any gain with the eddy heads other than the gain due to the weight as you mentioned.
