That grommet works fine on a stock motor, installed in the valley cover. I used it for 2-3 years. Including a couple with 4lbs boost on a Paxton blowing thru an Edelbrock 1406. But when I built the stoker motor, ran the boost up, more cam, and started going past 5000 rpm I need to build a real baffle. It really wasn’t a problem driving but when we were setting the engine up on the dyno we blew the head gasket on #7, and between 7&8. Yeah, twice, I’m a slow learner. Upon closer examination we found the oil in the intake passages. Detonation blew the gasket real quick. Adding a real baffle stopped the problem. But on a stock motor, I’d run it again in a minute.
