I have a set of 502's completely rebuilt with new valves, 5-angle valve job etc.

I want to run a cam that has a max lift of .548

I will need to do some machining to be able to do this and run roller rockers. Would I be better off selling them and buying Edelbrocks out of the box or using what I have and putting some more $$ in them.

I know you can machine heads to be pretty good. What the Edlebrock heads have is a 'modern style' combustion chamber. Guy down at the local speed shop swears by them on older engines. If you can afford them, I would say Edelbrocks.

If you've had the guides done, it may be cheaper to work with what you have. I'm not sure of the source, but there are bolt on roller kits, they may be too light for your application.
If you could get some reasonable loot out of your old heads, it may help the offset in price.
Either way you'll be buying rockers.

The guides are not machined yet. And I'm afraid with the aggressive lift I'm looking at the bolt ins won't work. I was thinking about Indy heads too but the guy who answered the phone wasn't helpful and put me on hold four or five times in just a few minutes and I just hung up.

I am leaning towards the Edelbrocks after some reading. I might sell my rebuilt heads and put that towards the cost of the aluminum ones.

If building a motor with massive heat potential, you may be better off with the Edel. The stock heads will do the trick, probably for a little less.

Well it might get a little warm offroad but the current set up worked well with the 30 over block and regular grade.

The Edelbrocks will bring me a hair under 10:1 which sounds like a nice point to build power from. I'm shooting for one horse per cube.
