What is the best bang for the buck with easy installation(no modifications) that has proven to have the least amount of problems?
It's a 446 9.5:1 with a Comp flat tappet with about 500 lift I got from fast68 Dwayne Porter. I know I will probably have to clearance for 3/8 pushrods if I don't use 5/16 ones.
Thanks mike

I shopped around on my latest build, and went with Harland Sharps based on previous good experience. Roller rockers usually hit the stock valve cover oil baffles, but we make a valve cover spacer for that if you want to avoid modifying your baffles.
If you want to run spark plugs with a 13/16" hex, you'll need to grind a bit around the plug locations: mock that up before assembly.
Somewhere - either here or at moparclassifieds.com - someone's selling a set of HS rockers & shafts cheap.

I'd find a set of Crane or Isky iron rockers.I'm using the Crane iron rockers on my Stealths and they work great.

I have had good luck with Crane and Isky iron rockers. But on my 493 I use Hughes roller rockers and they are holding up and working fine. Ron

Try to stick with a 1.5:1 rocker ratio. It will require less grinding on the Stealth head to clear the 3/8 pushrod.

I will say this...do NOT use 440source rockers. every set I have heard of...has ended in "roller tips got munched"

Comp cast alloy steel "pro magnum" for me at .55 lift. They are well made and durable. Good up to about .6 lift as shipped. Agree the iron should be fine also. Properly set up, there's no real need for roller tips at .5 lift.

What are the specs on the cam? If it's hydraulic and mild enough you might not even need the adjustable rockers.

OP asks for "best bang for buck", and there's two responses naming the most expensive rockers you can buy...... Moparts.

I've been running Pro-Comp Steel bushed roller-tip rockers for a few years now, and they still look and work great on my .575 lift solid. Crane Ductile steel rockers are great bang for buck, but above .500 lift, conventional wisdom says use roller tips. Comp Cams Pro-magnums look like solid value.

I'd stay away from aluminum unless you're spending big money. Seen too many budget aluminum rocker bodies break under marginal pressure.

With .500 lift Id use reg steel adjustables.Unless you are going to a bigger cam rollers would be a waste of $$$$$.I run an old set or Erson irons on my 440 with a .588 lift cam.3/8 alloy Crane pushrods.They just clear on my Stealths.Id say 5/16s should be good on that setup.Rocky

Dan at Performance Only recommended and is installing Proform #66868 on my .30 over 440 with 440 Source Stealth Heads. +/- .50 lift 500Hp Build.
Show car not race. Hope this helps. BBD

Thanks for the reply's
The cam is a SOLID Comp.(part # 21-0005) 502 intake 511 exhaust with 236 intake and 242 exhaust @.050 lobe separation 112.0 that I got from Dwayne Porter. This is a 30 over 440 9.5:1.Hoping for about 500 hp motor going in my 68 Charger street only car with 323 gears and a 727.Will the 5/16 pushrods be ok in this build or will I probably have to clearance the intake holes even with them?
I want something that you guy's have had good luck with and are not too expensive.I hope to not have to machine the head for them to fit. Sounds like the steel ones would be good for me but I do want a roller tip!
I had the cam Nitrided and have the solid lifters with the hole in them!
Thanks mIke

Rockers are not a place to skimp , more than one person , even though some will not admit it publicly , has had a CCJ rocker FAIL and grenade their engine .

If Dan is recommending the proforms then they must be a decent rocker , even though they are CCJ . Or the buyer is insisting on buying CCJ rockers against Dan's recommendations and this is one he is comfortable with.

There is not real hp advantage switching to a roller tip , but a set of Crane ductiles isn't really and inexpensive alternative anymore. What rocker did Dwayne recommend ?

Before anyone else climbs all over me about mentioning the HS rockers, I stated in my reply that there's a set available cheap.

I don't see any reason why you need to justify your reply to his question .

Since you mentioned bang for the buck right up front, I'd go with Hughes rockers. I have sold, and sell, a ton of Harland Sharps, and most people on here know I am a big proponent of them. They are hi quaility almost indestrucible rockers in their intended applications. That being said, they arent the cheapest option. They also really need to be ordered the same as the Edelbrocks. The rocker tip/valve centerline really isnt correct in the standard sets. I worked with H/S to come up with a proper fitting set for Edelbrocks and Stealths,but yes, at a higher cost. Since budget is a concern, then the Hughes in my opinion is the best bang for the buck. Comps are almost $700 now, so no deal there.Crane has priced themsleves out of the market as well. Used to be a good bargain, and since S&S, they have become too much for what you get.

I have tried the Hughes rockers for a more budget friendly,quality piece, and I actually liked them enough to go ahead and become a dealer for them based on my experience with them. So, long story short, I think they would fit you well.As far as Proforms, I would guess that was a budgetary decision between Dan and his customer and baseed that on the build and expected useage.They are not in the same league as these others mentioned.

No, they're not much less expensive than a set of Crane Golds. I bought a brand new un-used set of Erson ductile irons on here (same as Crane and Isky) for 200 bucks. Otherwise I would have probably gone with Crane Golds. I don't have much experience with them, but I know many people/engines that have run them with success and they've been around for years.

I've got a set of crane gold rollers for mine, however I only bought them because I got a great deal on them. I think even the crane ductile rockers list for around 350 bucks at summit.

With your relatively low lift cam, stick with the ductile rockers. You have no use for roller tips at .511 lift. A hydraulic cam of similar specs would have been able to run stock style non-adjustable rockers.
