Pro Mag rocker question

[TYHOGG]

I have the late model vortec swap #772 with arp 3/8" studs installed. Will the pro mag rockers fit under the newer style valve covers with the supplied poly-loc retainers? If not what is everyone using for retainers on these?

Thanks in advance,
Adam

no. wont fit.I have them with 1.65 rockers and the only trouble free valve cover ive found are sheetmetal ones. I cut out the posts and support inside the stock covers, welded new supports in on the top so they wouldnt crush when tightned but still clear the rockers. That worked but I had to remove the baffling.
