Harland Sharp Roller Rockers!
Harland Sharp Roller Rockers! Help/Info?
Went to Summit Racing today and what do I find on the clearance rack....a bran new set of H&S's for 318/360. They're $400. Got um on the clearance rack for $250! I planned on buying them in the spring for my 318, but I couldn't pass up the deal. http://www.summitracing.com/parts/csp-s70037
From my understanding these are the non adjustable ones that bolt right on. I'm not putting them on till the spring because my truck is already put away for the winter. I know before I put them on they need to soak in 30w for 24hrs and to use cam lube on the rollers and push rod cups. I've heard different things but want to know if they'll clear factory valve covers. I'm not putting a cam in, just the rockers. When I did my plenum two years ago I checked out valve train and everything is in great shape. Truck has 125,000 on it. Runs like new. I rigorously maintain it and do not beat on it real hard.
Any advice/tips/tricks from you guys that have put H&S's on their Magnums would be greatly appreciated! Thanks!

were there more? I've been contemplating these. Also, will the factory valve covers work even if you have swapped the cam? Thanks

Lol I knew there'd be some jealousy about them. Clearing valve covers, ok great! And no there were no more on the clearance rack. I saw them and figured they were for Chevy's because 90% of the clearance stuff all the time is Chevy intakes and heads. Walked up to them right after a guy was looking at them, saw they were 318/360 and snatched um right up. After I grabbed them I pulled out my phone and went on my Summit account....won'tcha know the ones I had on my wish list were the same part number I was holding in my hand. I felt like I had found the holy grail lmao

ha... jealousy is a strong word.... Nice grab. I was just hoping there was a pile of them, and you could make some money off me for picking them up, lol.

yes it'll fit but you don't want to use fixed rockers with a custom cam! Get the 1.6 ratio adjustables, and guide plates, and hardened pushrods, and rocker studs to mount them. And no the adjustables will not fit the factory valve covers without cutting the baffle to make room.

When I did my rebuild, I used the following pusrods. Are they good, or would I need to upgrade again?
Melling Pushrods
MEL-MPR-462
These Melling OEM replacement pushrods are perfect for stock rebuild or mild performance applications where open spring pressures do not exceed 300 lbs. They are manufactured from steel tubing and work well with stock or aftermarket rocker arms.
Mopar Performance Valve Springs
DCC-5249464
Valve Spring, Single, 1.418 in. Outside Diameter, 1.640 in. Installed Height,
Mopar Performance Valve Spring Retainers

If you have a stock cam they will be perfect, As said it's when you get to custom cams non adj rockers are a bitch...Good move on the spring upgrade.
You can run 1.6 or 1.7 rockers with a cam, I've run both....just pick a grind that will work.
