By 1974 wouldn’t all heads have been built with screw-in studs?

Sticking your finger down in the oil filler cap hole will confirm that pretty easily.

Years back I pulled a few sets of #46 off 350 2bbl engines to resell due to calls wanting them after the headflow test came out in HPP magazine.
They were all screw-in studs , but I don't know if that was luck or not.

I just checked my limited sources and '73 350's (all 2-bbl small valve heads) had pressed in studs while all '74 V8's got the screw-in studs.

B-man, I think you are right...the switch to screw-in studs for all heads was '73(?). I'm forgetting those details as I get older...

If so, I hope Ken's 350 has the 46's...easy GTO engine conversion. It sure would be a great candidate for some '70 #16's with 78 cc chambers. The 350 doesn't really need to big valve heads for more power, but 1.5 points in compression would certainly help.
