Re: "A" heads on 59AB block

None, you will actually gain torqie. The "A" heads have less volume and the 59 series engine has more cubes. The small amt removed for valve clearance shouldn't be a factor.

I have a set on an 8ba milled .040" measured CR is 7.2

Hummmmmmmmmmmm. I just put stock Mer heads on my 8BA (also Merc crank/pistons) I know I gained cubic inches but what did I gain or lose using Merc heads Vs. the 8ba?

Thanks in advance.
