you guys are all over-thinking this. It's a friggin' driver 383. Use what you have except the cam. If you haven't bought the e-heads Don't. They are overkill. Grab a summit cam and a good set of used iron heads and roll. You are going to use mani's anyway. You won't be able to tell the difference. Quench? really? On a 330-350 hp motor? who cares. It will run fine. Jeeeesh some people like to make this way to technical. Plenty of toss together 383's and 440's running fine w/ many many miles and many many passes with little or no attention to all those details.
Don't know what the guy is saying about thread sealer on your head bolts...you coat them with oil and put them in. If you run e-heads the studs are better. You do however need to run sealer on your mani' studs. I use teflon tape on mine. Good luck with the build.
