All the Mopar V-8 rockers are way too short, and the pushrods(if you're using 3/8 chrome
- moly), are already perilously close to the head near the deck. There is no room for that with1.6 moving them in even closer. That IH rocker looks longer and to be a 1.7?? ratio, i'll have
to check on shaft dia. & oiling provisions/design. 8 bills from T&D don't sound bad if that's thecase, depending on what is included, the PP&R's have billet hold-downs,shaft,spacers etc. sothe extra $230 may involve those items....
You can grind clearance for the p-rods, but I don't think near enuff for a V-8 rocker,not
to mention moving the shaft that much isn't feasable or complimentary.As far as SB shaft
diameter, it shouldn't be too hard to hone al rockers up if they were an opt.
