Just curious, what is the average cost of AFR heads?

The 265's are considerably less than the bigger 305 and 325's. I would strongly recommend upgrading to the inconel exhaust valves. Also, if you are buying them fully assembled, it might be a good idea to have guide to stem clearance checked, especially if you plan to run it hard with raw water cooling in a body of water that has cool water temps. That goes for any aftermarket head, not just the AFR's. There is an epic (now closed) thread out there on this - 'nuff said.

Ok so here's the plan. I spoke with my finance manager, a.k.a "the wife" and got the go ahead to tear them down. If the current heads are in good shape going clean them up and reuse. If they are cracked I will be replacing with Elderbrock marine heads. It currently has Thumper Power manifolds and I'd like to keep to save some cost. I plan on sending the rotating assemblies out for balanceing and inspection. Hopefully I can rerun the pistons but not a big deal if not. My goal is 500HP at not rev past 5,200. I will be converting to roller cam and replacing the crane gold lifters. Probably run a air gap intake and definitely going MSD distributor. My budget is 5k per motor, but any money I can save here will be spent on other updates, gauges, interior, paint and probably rebuild the transmissions. So my main question is what cam to run? I don't see blowers in the future, just don't want to deal with them.
