Oh, it's been done. And still being done.I'm pretty sure somebodys tried it already. Whats the youlube say?
Any gains from that?
Maffs aint my strong suit, but I aint sure you can flow any more air from the 2 big valves than you can from the 4 smaller ones.
Advantage might be in the pattern, swirlies and such.
There are scientifical terms for whut ah mean I'm sure.![]()
A well ported 12v with big valves will out flow a 24. There's also more valve gear in the 24 to rob powa. Not as drastic of an effect in a diesel as opposed to a gasser though.
