Anybody ID RHS heads?
Hello,
Have a line on a 400 sbc with RHS heads, at least it says RHS in a casting in between the rocker arms.
The only nomenclature I can find on the heads is the numbers 223 4000 00 A.
Don’t know if these are old Protopline, Proaction or whatever when RHS purchased those companies.
They are not nearby to examine.
The old interweb describes RHS heads as of varying quality depending when they were made & by who, before.
I would just like to know the specs on these things if possible.
Thanks.
