How much does it cost to rebuild a Slant 6

IMO, for a stock rebuild I would not get hung up the older vs. newer head from all I can read. Port flow is not much different, it is just that the later head has more possibilities for improvement due to some chamber details. The older heads are not more prone to crack or warp or have valve seat issues that I know of.

Sounds like you have the right guy for this work; our local guy is similar. I have to take a pix of the shop front someday; it is a classic! But the place is PACKED with machines, parts etc. It will be a sad day when all the older machine shop guys retire.

BTW, I assume you got new cam bearings installed? DON'T skimp on this!

Thanks for all that info. I have read that article by Dutra on heads which is how I got side-tracked in the first place. IIRC he said there was a dead area in the early chambers. I'm just trying to take advantage wherever I can.

Yeah, new cam bearings installed. he also put the freeze plugs in. Just like your guy, he has a little bit of everything. When I was there on Sunday (yep he was there) I saw a complete 239 C.I. Ford flat head engine but it was scattered everywhere, a 400 Pontiac, small aluminum 4 valve Honda heads, John Deere tractor block, snowmobile heads, Harley heads, 5.9 Cummins rods and parts for a guy installing it into a Chevy PU, just too much to take all in. He doesn't grind cranks but he gave me the name of a guy up the road who does most of them in this area.
