I have been searching around for a while but I have a specific question and I can't find the answer for it. A good friend of mine bought some roller rockers a while back for an LT1 project. He has decided to go another route and no longer needs them. He is willing to give them to me for next to nothing. SO my question is will they work on my stock L98 heads? Do I need to change anything else or can I just remove the stock and replace with the new? I already have a set of tall valve covers, but, do I need them?

They are the Crane Cams Gold Race Extruded Billet Rockers, part #270-10758-16

Info: 1.60 Ratio; 3/8'' Stud; LT-1 & LT-4; Self-Aligning
Increased 1.60 ratio with a standard 3/8'' stud diameter. These are narrow body rocker arms for centerbolt valve cover heads. Cannot be used with a mechanical lifter camshaft. These are sold as a full set of 16.
Applications:


Chevy V8 305-350 LT-1, LT-4 1988-95
Chevy 90° V6 4.3L 1987-91
Note: For use in self-aligning applications only. Do not use with pushrod guideplates or with cylinder head castings that guide the pushrods, as severe pushrod wear will occur. Not for use in LS-1 engines

Thanks

 

They should work just fine. The valvetrain is basically identical.....go to Summit's website and look up the Crane Gold's for TPI and see if the part number is the same.
