Same here

 

Thanks guys, that's what I ended up buying.

 

Since you have 'self aligning', there's no need for hardened pushrods anyway..

 

I see some of you are running the GMPP 1.6rr sa. Do some of your rocker arms sit on the retainer?. Some of mine do and some dont. Ive tried cranes 1.6rr sa also and they do the same thing. Are any of you have the same problem?. Im going to switch some pro mags with a slimmer arm and that she be ok I hope.

 

I had the GMPP Hot Cam rockers when I got my LE1 package and the shoulders rubbed badly. I switched to Pro Mag SA and haven't had a problem. You will be fine with those I'm sure. You just have to take out the valve cover webbing if you haven't already.

 

Ok, so it seems im not the only one with this problem.

 

awww crap... so i shouldnt get them then? i was planning on having a mechanic whos installed rockers b4 install em too.... i was told there not a bad rocker.. and well i already purchased them....


webbing?????

 

Not saying you shouldnt get them but be forwarned that this may happen to you too. I had the same thing happen on two seperate heads with those rockers. Id get some promags.

 

The crane SA 1.6s worked nice on a previous project car.
I went with NSA promags this time around because I used a more agressive cam.

 

if the pros work better then i will return these and get those then.... as long as i dont need to buy anything else i will get those.

does this all sound good? :

16 Comp Cams Pro-Magnum Self-Aligning Roller Rocker Arms, 3/8" stud, 1.6 Ratio
LT4 Spring GM PART # 12495494
Valve Spring Cap Kit, LT4 GM PART # 12495492
Engine Valve Spring Cap Key GM PART # 12495503
Valve spring shims GM PART # 10212809
3/8 Stud Pkg GM PART # 12371058 (doubt i need these i was told)

 

Are the 1.6 GMPP that ****ty of a rocker? i mean ****.. if the hotcam uses it.. and theres not much trouble with those.. i thought this would be a good rocker.. since i dont plan on camming this car... got other things to worry bout... I just want a I/H/E, and maybe a little juice at the track... would the 1.6s suit me good? Even if they rub... is it that bad of a thing? I thought most rockers do though?

 

Nothing shoud EVER be allowed to rub in that area of a valvetrain(major problem waiting to happen with all the additional harmonics and stress it could cause on parts)........And In my opinion , even for your described useage, I would return what you got for the 7/16 size comp promags(They're a much stronger and better designed rocker) I would also spend the 25 bucks and pick up the larger ARP 7/16 studs to go with them....small price to pay for a ton more strength, but thats just me......good luck with it......

 

1.65 Morels here... (but a solid roller setup)

 

I have the Crane Gold 1.6's with LT4 springs and retainers, and they don't rub the retainer at all..

 

Whats the part number for GM Retainers? and ****.. if i install them fine... im sure they'll work good... dont alot of people use the cranes
