Good classic camel humps. Not sure if they have accessorie bolt holes? If i'm Reading the date stam pkorrect the head shown is from november 71. That should mean accessorie bolt holes, since the long pump came in 69 in cars. Pickups and Corvettes still had short pumps I think.

That would be relevant to me at least. I guess you want to keep everything else (water pump, pulleys and brackets).

The "64cc" would mean just under 10:1 compression with a standard block (Ø4" , not decked, .040" gasket).

Those valves could be 2.02/1.6 which is really good. 1.94/1.5 would be still fine.

Screwed in rocker arm bolts is great!

The springs are single. The flat sping inside is a harmonic damper spring.

The valve seals look new.

I would try them on.
