If not will scorpion roller rockers clear??? those are the ones im looking to get for my build-up but havent made the purchase just in case they dont clear the valve covers??
YES... there are a bunch of threads about this very subject on here. I have 1:7 crane/Cobra ones on my car with the stock covers. No clearence issues at all. No mods to the inside of the cover. Just a regular rubber/cork gasket.
I installed 1.7 proforms a couple weeks ago and got them to fit by working four of them a little. I used a dremel and ground an angle on the ones at each end of the head so the VC would fit. I also used a double thick VC gasket. I didn't have to remove the oil baffle. I took pics of what I removed from the roller rockers but they're at home. I'll have to post the pic later.
