Yeah I measured my studs and they look to be 1.9" long. I see the ARP 334-7203 are longer stud. 2.1 tall. That would make the straub measurement a bit easier. I ran out of time but it looked like I could just barely get a 1/4 turn of thread on with the rocker at the 90 deg point.
When I get back to it I will see how close the Straub method is to the 8.75 pushrods I have in there..
Here is my math on that.
Gross Lift on the stump puller .570/2 = .285
7/16 stud 20 TPI .05 per Turn
.05/.285 = 5.7 Turns past baseline

I'd be surprised if you need 2.1" studs. That's what I have on my race motor with 1.95" spring installed height.
