hi every1 my heads are in the shop gettn milled down for guide plates and rocker studs, does any 1 know the exact part number of rocker studs i need?? im going with 7/16 harland sharp rockers, i looked online and theres 2many different oldsmobile part numbers 2 choose from, i dont want 2 spend $150 arp's thank you

 

Why not get the 5/16x3/8 studs. How much spring pressure are you going to have? Most applications will be fine with the Comp Cams style conversion. Otherwise I don't think you can find 7/16 studs without tapping the existing holes. Again depending on the application not sure it's worth it.

my PP damper just came it sure is nice for 200 shipped i just ordered another 1 and im sending back the 600 one i bought for my other motor, thanks again for all the guidance mark!!!!

 

I have done heads either way,and you don't need to mill the pads for guide plates.You could just leave them alone,and use the Harland Sharp shaft rockers.No guide plates,machining,or special treated pushrods needed.

 

I'll get you the part numbers, just pm'd you. All your stuff will leave Erson tomorrow.

Thanks
Mark
