That a little different the iinfo I found, they said 62 2.08 became standard equipment, but really don't matter. Obviously they didn't overly care about cid and valve size if all performance 361/383/413/426/440 came with 2.08 and basically most standard performance engines.

And really not proof for buddy was my point.

Factory BBM heads are shitty stock, chamber shrouding etc., bigger engine bigger cam.....easy peasy for them & no multiple valve part#'s to mfr....., Mopar knew what it was doing......saving $$$$ & providing an ample size intake valve for the bores being used.
Now go back to keeping the mice all circling in the same direction.
