Edelbrock heads on a 340 with KB243 pistons

Yeah, I'll get on Summits site and order some at .053, that way I'll be able to use these heads. I really want a good quench because my Dads going to be driving it and he won't put the greatest gas in it. Just trying to make it as seamless and bulletproof as possible. I got a great deal on the heads so I want to put them on something. I might dig through my pile of cams and see what I have, there about 10 new ones laying out there so hopefully I can find something that makes a little bump without vacuum problems. I might buy a Fitech unit to put on this engine also. I just want it to run out pretty good and not give him any problems. At 83 years old, if he has a problem, it will surely be my problem.
