I sure do. Around 76' i bought a jig to pin the studs after slightly pulling a few on a couple pair of early 327 heads. I actully did one set and then thought, what the He!! are you doing. After that i just had the shop mill'em, drill'em and used screw in's and guide plates. Even with the studs secure and using moly pushrods, i still had valvetrain issues. Glad i learned my lesson early as most of the work i did on them was for others....lol.
