There are already legal Eddy replacement heads for FE Fords, Olds and Pontiac, but those versions are OEM valve size.
I can't imagine the BB head ever being legal with a 2.14/1.81 valve combo, but then again NHRA is stuck on STUPID sometimes...ah most of the time!
But the Eddy SB LA Mopar head is OEM valve sizes, right?? Hmmmmm....
