David,
Is an improvement of the down draft angle one of the reasons that the heads for the LS series of chevy engines have less valve angle than the traditional SB chevy? (15 degrees vs. 23)
Does this also explain (at least partially) why the LS1 engine's cylinder head uses a larger port (in terms of volume) than most, (if not all) production SBC heads even though the displacement of the LS1 is only 346 c.i.?
