I've got a pair of 452 casting cylinder heads that I thought came off motorhome engines, but my mate says different. He reckons they are for all engines approx '77 onwards and 86 or 88cc chamber and I think they are 90cc. Is there a chart or listing with this info?

I read somewhere that R/RB heads have either 74cc, 80cc or 86 cc chamber volumes. Is that correct? Do you always call 74cc heads for closed chamber heads and 86 cc heads for open chamber heads? What about the 80 cc heads then?

Never seen any that were 80cc myself.

They all seem to be around 75cc (closed chamber) and 85cc (open chamber) with some variation by a few cc's due to low quality control in manufacturing.
