P.S. I did pin a lot of studs but it was at least 30 years ago and a lot more....

Yeah......about that. I also hadn't pinned any studs in a long time either. Racers moved on to better options.

Then......the Magazines and the Internet "Experts" convinced all these streetcar folks that they needed Vortec heads as a "budget" performance option. You put one more ounce of spring pressure or cam lift on those things. and the studs seem to fly out. Once they see that the guides have to be cut and new seals installed, there's no room in the "budget" for screw-in studs. Now pinning becomes an option again.
P.S. I can't describe how much I dislike pinning studs nowadays.
