Which roller rockers from where?

I bought some Comp Cams Magnum roller rockers for $150 at summitracing, not a bad price especially since they're listed at around $220 on the Comp Cams website.

With those heads, unless you've had screw in studs and guide plates installed, you're gonna be limited to pedestal type roller rockers. The Crane Energizers are a good choice there. I've been running a set of used "Cobra" roller rockers ( 1.7 ratio and the equivalent of the Energizers) that were made for Ford by Crane, for about 2 years now. I bought these used from someone in Michigan and have no idea how long or how many miles he used them. They've held up fine, no problems.Also suggest that you port out the exhaust passages on those E7's before doing a valve job on them., They'll work much better with that cam after doing so.All that's needed is to hog out the sides and roof about 1/8" to 1/4" and blend them down into the bowls. You can leave the stock valves if you choose. This is what I did to the ones on my 89 Ranger's 5.0, and they work great.

Ford Racing.

I've had good luck with several sets of the Ford Racing "blue" roller rockers. As was poited out you will need the "Bolt Down" type unless the heads are converted. There is a high likely hood that the Ford Racing rockers are made by Crane. I'd shop mostly on price on this one as long as you are dealing with a known brand (Ford Racing, Crane, Comp, Erson) with equal features.

I've always had great luck with Summit Racing.

Yes, unless like I said before, you or someone else has converted the heads to screw in studs and guide plates. If you go with 1.7 ratios, you'll pickup a few thousands lift at the valve over 1.6's.
