W2 heads I think they are ready
Its a modified Moroso stop, I carry a 7/16 wrench behind the seat for quick adjustments its been very effective winning two track championships with the setup. Last year I tried a Willys adjustable plate system but couldn't get it to work properly on my combo so I went back to the bolt type system. Slows my car down from 10.70s to 11.50 @ 114 w/ 1.49-1.52 60 ft Shallow in bracket mode, 11.50 @ 114 w/ 1.60-62 60ft Deep in index mode. The Moroso stop bolts to the right rear carb stud, I found that it would move slightly and didn't want to overtighten the carb stud , so I went to a Jegs throttle cable bracket and drilled another hole in it by the carb stud so now the stop can't move with two bolts holding it
