I'm collecting parts for an eventual SE boat, and been reading the dyno threads and talking a lot with the local engine builders. Given the SE rules, the Vortec head is legal, and one would think the new technology would be a good thing. However, I've learned a few things from GN7 and others that makes me think they would be the wrong way to go, because with the big gasket and the flat top pistons, you do not get an effective quench, which seems incredibly critical to making a good, long running engine.
So if the Vortecs are not the way to go, does anybody have a line on the best heads to grab? Which ones provide the best quench within the SE rules?
