I should have clarified that I was speaking about open chamber W2's. I posted several times that I pretty much detest the closed chamber designs (I would be in the minority here but I stand by it) so if you have open chamber heads and a zero deck you are talking .090 or so quench PLUS THE GASKET so in total roughly .130 quench. I'm not anal on quench like the Chevy guys but that is pissing away power. And , you could go from 9.5:1 to probably 10.5:1 and gain power on the same quality of fuel just closeIng up the quench.
That was my point. My first 340 in 1980 almost came to a fist fight because the prick doing my machine work wouldn't deck the block and put the piston .040 out of the hole. He was and still is too stupid to think outside the Chevy box. Because of that prick, I started doing my own engines, then machine work.
Yes, I hate that prick on several levels.
