Hey fellas anybody use these Harland sharp rockers on the eddy heads or their sbc heads?? Are they any good??
I've not heard much wrong with true HS rockers. They have a couple different series http://www.harlandsharp.com/sbc_38.htm
I think these are the ones the guy has? Only issues is if they are then they're only good for a max spring diameter of 1.450 and the eddy head springs are 1.55 diameter so I don't think I can use them? I msg him asking for a part number. I think I would need the SH1002 wide body ones instead of the S1002. https://www.summitracing.com/parts/csp-s1002
So I found a guy who is selling a set of comp cams pro magnum ultra self aligning roller rockers. Here's the link to what they are. Anyone use these? Are self aligning easier to use/set up? Are they quieter? I checked the specs and they fit springs up to 1.54, the springs in the eddy heads I have are 1.55 will these still work? https://www.summitracing.com/parts/cca-1618-16
You still might have spring clearance issues. This is typically the difference between self alignment and not. You won't want to use guide plates if you use this style rocker. They will still adjust the same way as far as lash
I would want to buy rocker that say they clear 1.55 or 1.56 or even larger sprung diameters. Good deals do you no good if they don't clear the springs
Thanks Ben. From what I see and understand in your pic the self aligning rockers are easier to use as they kind of set themselves up and I would just adjust the lash. I could probably clearance the rocker body a bit for the spring it's only 0.01 smaller, 1.54 to the 1.55 correct?
I've been waiting for a guy to get back to me on another set of the orange Harland sharp roller rockers, he said they fit the 1.55 or larger springs. I stumbled across these comp cams ones and thought I'd ask about them.
I've been thinking lately about spending the extra money and going with shaft mount roller rockers for these heads, possibly Jessel? Anyone have and suggestions or part # for make/brand? Again they need to clear the 1.55 springs.
Possibly lol. I was just thinking for easy of installation and not having to tweak every single one,using the adjustable guide plates and having to notch/modify them for a quieter valve train? Plus the extra strength of the shaft style rocker oppose to the stud mount rockers.
Does anyone make a shaft system for these bbb heads??. I dont think a regular sbc system will work.....the valve spacing isn't the same so the base for a stand sbc that bolts where the studs goes won't fit, and then the shaft pairs that bolt to the bases more than likely won't be over the valves due to the spacing of the valves. And you still need to adjust every valve indivually just like you do on roller shafts systems for our bbb heads. Plus at like 1200 compared to 300ish........im not seeing this idea be a great one. I have seen jessel system add to TA heads after they cut the stands off and other mods to make them work....but not yet seen them on bbb edey heads
Ahhh yes you're right Ben the valves are in a different location compared to regular chevy heads. I thought I read on here somewhere about someone using shaft rockers on their eddy heads to help aid in keeping the valve train noise down?? As for the cost, yeh it's not really worth it to me at that price. I was just thinking if I could get a good set (even used) for a decent price and it makes it easier and quieter then maybe that would be a good alternative route to go. Back to the drawing board .
Way over thinking this for a street motor guys.. All you need for excellent durability, is to step up to 7/16 studs, go with the comp cams pro magnum roller rockers, and a set of adjustable guide plates by Isky to correct the alignment issue, which causes the noise. Anyone who thinks that doesn't work, I will give you the phone numbers of the customers of mine who own these engines, and have no valvetrain noise, or issues.. for years now.. Beware of anyone trying to BS you with the "theory" of why this won't work. JW
I agree, done several and with the adjustable plates the noise is minimal. The rockers are excellent or Harlon Sharp and are plenty strong. KISS.
I'll decide between the comp pro magnums or Harland sharp rockers but the adjustable guide plates are happening for sure no matter which set I choose. Thanks guys for steering be back on track.
So I came across a guy selling these Jegs 1.6 roller rockers, brand new with the 7/16 studs and lock nuts for $200CDN. Anyone use these before and have any info/opinions on them??
Can you use 1.7 ratio roller rockers with 7/16 studs on the eddy heads or is the recommended 1.6 the max?? Any pros/cons??
