GM rocker / valve cover studs part number?

[Jan Larsson]

Anyone got the correct GM part number for the OEM rocker / valve cover studs? I got the old part number 25519860 but nothing shows up on that one anymore so guess it changed?

Valve cover studs are discontinued. I do have a new set of Harland Sharp 1.6 rockers still in the package they came in. I'd like to get some 1.7 ratio. Let me know if your interested. I gave $360.00 plus shipping. I need to get somewhere close to that or I'll just use them. Thanks Mike

What ratio are the stock TTA rockers?

When we rebuilt my motor we measure them to be 1.6 but I.m sure other people have had slightly different calculation results.
