Two questions on heads. New Hemi guy trying to learn. Early 70's AFR heads from boat.


Hey guys trying to learn my Hemi's. I found a set of 1619823 casting heads built and ported by AFR complete. Early 70's vintage. O ringed 2 1/8 and 2 1/16 valve. Think he might of made a mistake on the exhaust valve size. I haven't found much info on AFR Hemi heads on the Net. Any comments?

Also a guy local has a set of bare truck heads 1730438-1, can you guys tell me anything on these heads PRO/CON?

The truck heads usually have sodium filled valves so require a bit more work for our kind of use.
