Decent Slant 6 carb, intake, header setup

I know this is an older posting, but I am getting closer to doing some changes to my 225. I would like to remove the head and have some work done. Therefore, I think it would be best to find another head to work on while I keep driving my car. I have been told that 68 or newer heads have a better chamber. Is this true? And, would any of the newer heads work with my solid lifters? Also, should I use a copper head gasket and new ARP bolts?

Same head bolts, all heads are interchangeable only peanut heads (dont have drool tubes and you have to remove the head to get to the lifters), and yea 68 and up heads are better, i used the stock fel pro Gasket mill that head .100th i went from 7:8 CR to 9:1 CR just with the mill. Also measure piston height at TDC and CC the heads to see if they never been cut, i ported out three heads with amazon carbide bit 20 bucks dont go crazy just clean up imperfections. Hit the floors on the ports. i say you get two heads a good one and a junk one to practice. Also clean up the threads on the head bolt use some PB blaster to chase them down or else you might snap them when torquing. Doing this alone is better than just slapping on a bigger carb, next would be a camshaft swap. GOOD LUCK!
