So, would the problem with using the ZZP rockers on earlier heads be that the mounting studs are the wrong size? Can this be worked around?

Keep in mind, the L27 and L67 starting in 93 had roller fulcrum. This was maybe only a 5hp gain over the 92 L67 and L27. The gain is from the ratio itself. Even the roller tip won't gain any amount of horsepower you could characterize or claim.

I gained 2whp for going to roller tips on 130lb springs. NO other changes! And another 11whp moving to 1.7 rr'*.
