I am putting together a 400 and have some questions on quench. Currently planning on using a set of 061 heads. These are big valve and CC at 79-80. Installed screw in studs. These heads have almost no quench pad area. I'm planning on flat top pistons and zero deck. So will zero decking make any difference since the quench pad is almost nothing? Will the lack of quench make this motor more prone to detonation? Compression calculates at 9.8 at zero deck or 9.6 if I leave the pistons .01 in the hole. Cam choice is 2802 but subject to change. Goal is a ping free pump gas engine. Looking for advice on quench factor.
