pcv baffle

I put roller rockers on my 302, and valve covers with no baffles. I thought I could use a baffled pcv grommet, but the bottom of the grommet contacts the rocker before it can seat properly in the valve cover. I need about another 1/2 inch of clearance. I'm using the Moroso tall-style valve covers, and they don't seem tall enough. These roller rockers take up a lot of room, and the covers just barely clear them. If anyone has had this problem and solved it, please let me know.

Thanks,
Bud

What I did on mine (same setup) was use the regular grommets but found a push in baffled breather for the vent side. On the PCV side I only opened up the blocked off grommet enough on the bottom to allow some flow but not enough to allow oil to splash on the PCV valve.

You guys are scaring me!
What rockers are you running?
As my sig say's I'm going with rollers as well but have to use stock height covers due to my EFI.
BTW, I am leaning heavily towards the Harlands.

Hey moneypit, I am using the scorpion roller rockers. I measured the height of my vavle covers at the exhaust end to be 4 inches. I have heard of cases where roller lifters could not be used with stock 5.0 efi because of lack of clearance between the valve cover needed and the upper intake plenum.
