Hot Rods M/T valve covers seem kinda cool again.

    The early ones are cool, but the later sbc have the breather holes located over rocker arms. If you run a pcv valve the engine WILL burn about a quart to every 50 miles. I plan on running the early covers on my model a since the pcv will go to the rear of the block.

    You realize the new ones come with baffles or you can make them to fix this?

    The ones I had bad experiences with had only a plate to act as a baffle. The plate is common to all of the aftermarket covers I've had, m/t just put the pcv in a bad spot. I try to use the lt1 z28/corvette covers on all of my engines because the baffles in the original covers are hard to beat.

    There were 3 different style baffles MT/Holley used in covers. There were 2 different width rectangular with lips on the edges and a flat round one. The rectangular with the larger lips work best. I think I still have NOS baffles around here somewhere......

    Dug some old stuff out to show the differences. What you're looking at are original replacement parts for the SBC and BBC covers (241-217, rear) and everything else (241-216, front). However, throughout production the main differences (regardless of application) was the width of the baffle and the lip height. I've had the best luck with oil control by using the narrow baffle with the taller lips (241-216). Though it's narrower it seems to shroud the PCV better than the wider one with a shorter lip.
    BTW, the main difference fit-wise is the Chevy cover baffles had slightly narrower mounting screw centers than the others. You can use non-Chevy baffles if you take a rat tail file to the slots.

    While I agree with Blue One (I always preferred the finned Z-28 covers), I had to buy
    these special "350 LT-1" covers. They were $25.00 for the pair. Like most everyone
    else, he just wanted them gone.

    I can't think of a time when M/T valve covers weren't cool.
