Quite a bit less than AFR. I have not looked into RHS heads yet.
I would LOVE to have a set of AFR, but they are out of my price range.
I have used RHS heads on a few projects. Their pricing isn't as high as AFR, in fact their iron stuff is fairly affordable, and with a much higher level of quality than the cheaper import stuff. Definitely check out RHS and see what their aluminum BBC stuff is running.
That being said, I don't mind the cheap import aluminum so long as a qualified machine shop goes through them. I've used several sets that were what people would call junk import heads.
The difference is that I had them checked out and assembled by a machinist using quality parts. Under those circumstances, I had no issues.
Thanks!! That is good to know about Profiler. I had not heard of them before. The Car Craft article really caught my attention, but I did not know that Dr-Js was buying somebody else head and working them, I thought it was their design. Good to know. I am going to consider these heads first!Those heads arent exactly just Dr Js. He is buying them from Profiler and assembling them.
Profiler is a well respected brand, just not as well known to the general public as some of the other names that have been mentioned. Those heads that you linked to were designed by Darin Morgan, who is the cylinder head specialist for Reher & Morrison, and actually teaches classes on head design. http://www.darinmorgan.com/
I would expect them to be a very good head and have considered picking up a set myself.
The smallest BBC head that RHS offers has a 320 cc intake runner, which is really too large for best performance on a street engine under 500 cu in.
