AFR heads
Hi all, first post here. I just picked up an IROC with a ZZ4 short block and AFR heads. Trying to figure out which ones they are as owner had no specs on them. The only stamping I can see are 195. 3H, on top of that is 621 F. Any help would be appreciated. Thanks

Re: AFR heads
No other numbers on the front or back of the head casting? How about under the valve covers?

Re: AFR heads
Doesnt sound like eliminator series so it must be an older casting. 195 may be the afr 195cc heads pre-eliminator
