The end of October I started the thread “What Cylinder Heads?”
I just thought I would follow up and post what my brother purchased for his build. He stated that all your discussion and pointers were helpful in making his selection. In his own words:
“AFR Heads won the battle and got my business. I was getting pretty
comfortable with the idea of using RHS cast iron heads, but unfortunately RHS's tech support fell very short, matter of fact missed the bar entirely. I wanted detailed tech info about exhaust valve seats and port options, and the rep just didn't seem interested in providing it.
Conversely, at AFR I hooked up with a guy named Jeremy (ext. 111) and he seemed to be design level knowledgeable about his product. They pretty much were able to build my heads to the spec I was looking for including the hard anodizing for the marine application. This was all it took to know I was in the right place, and I bought them. Part of the reason the AFR's seem to be on top of th power game in the tests is that the valves are rolled another 2degrees from the standard 24deg. I never knew this before.
Don’t ever ask how much I paid for them, because I'll never tell... "
Bought 2 sets of AFR 2001 335cc full CNC ported alum heads through Flatlander Racing.
- Hard Anodized
- Inconnel exhaust valves
- Flat Mill to get 114 chambers
- 2 deg rolled valves
- Springs for .632 Lift
