Old AFR Heads as cast identification

Post by Justa1time »

Good Evening,

Anyone familiar with these AFR heads? They have non adjustable AFR guideplates. Exhaust ports significantly larger than 1 5/8" dougs you see in the photographs.

This engine was built back in 2004-2007 era.

Thanks,

Bryan from Oregon

1050 is one of the part nos in the AFR210 range. I wouldn't know how the current specs compare to heads as old as yours.

Are yours CNC ported?

Call AFR. The bar code will allow them to give you the complete specs.

Re: Old 2004ish AFR Heads cnc ported version identification

Good evening,

Fatman: Mine are Cnc'd.

65 Dragster: I called AFR- they don't have records this far back.

To give an update for anyone else who runs across these I still don't have a definite answer but mine are as follows:
- 2.08/1.60 valves
- 75cc chamber
- 214cc CNC ported intake
-74ish cc exhaust.

I am having a tough time deciding on keeping these heads for my 400 or selling and getting a new set of 195s. There are three things I do NOT like about these heads

- Angled plug configuration
- 1 3/4" exhaust port exit
- rocker studs do not share the same center as valve stems and at .645 lift and building up to the roller skids partially off the valve.

Thank you,

Bryan from Oregon
