You should be ok with proform.

i have proform roller rockers for my vortec heads and they are very loud!! if you search other posts on this site you will see that it is common. i bought the proform valve covers to match for vortecs and the rockers actually rub the side of the valve covers. you think that they would make their parts more compatible.
that's my experience anyway.
good luck.

The thing to pay attention to when using lower end rockers is what your valve spring pressure over the nose of the cam is. The lower end pieces tend to use lower end trunion bearings and they just don't hold up to higher pressures. If your cam is fairly stock with mild or stock valve springs then you should be ok. If you're using a solid roller with rollerish type spring pressures then you're asking for trouble.

just one mans experience. i bought a set of proform pushrods trying to save a dollar. after 250 mile on a fresh rebuild it ate three of the end off the push rods. i now run comp. everyone i talked to after this happened to me said pro form wasn't all that great.

Proform makes fairly good non critical components, but I personally would not use any of their engine critical parts like rocker arms. My money for roller rockers would go to Comp cams.

Crane Energizer rockers can be had for about the same price and a lot more peace of mind. I replaced some Proform rockers with them once and it fixed the "noisy lifters".

I have personally run the Proform "blue" rockers. They are loud and not built well (sloppy). This was years ago and maybe they have gotten better. I wouldn't give you a dime for them, they are right up there with CAT rockers (junk in my book). Crane Energizers as mentioned above by Larry are a good inexpensive rocker.

I have had good experience with Comp, Crane and Harland Sharp. I ran the Harlan Sharp rockers for 3 seasons in a 8,000 RPM small ford with a 700 lift solid roller. I sold the car after that never heard of a problem.

Pro Form Rockers

I put Pro Form 1.6 full roller rockers on my 383 stroker. They are noisy as heck and I had to grind some off a couple to clear the valve covers ( cast aluminum ). So far no problems other than the noise but the clearance issue had me worried when I first started the engine and heard the banging inside the cover. They are cheaply made and I'm thinking of replacing them with Comp Cam units like the rest of my valve train.

I use the Crane roller rockers,I don't think the small difference in price is worth going to the cheaper brand.
Crane has a good track record,and good tech support,at least they've been good with me.
