This exactly, although 3/8 studs will be more than fine for a 500 hp build that will see less than 6500rpms IMHOAre you sure those are ARP studs? The AFR's are notorious for breaking their stock 3/8" studs.

i upgaded to 7/16 rockers and studs....ya everyone seems to have different opinions...ill read what it says thenWhy did you get all new rockers? You can purchase them individually. As far as how far to turn after zero lash, that should be specified in the instructions the rockers come with. There are lots of opinions out there but somewhere between a 1/4 min. to no more than 1 full turn after zero lash is what i've read. After zero lash the amount your turn is the amount of preload your putting on your lifters.
And to add to that when you do it initially it may feel to tight when all said and done. i rolled the motor past the stroke where i was setting that valve and rolled it back to the point of where you can adjust it and re checked it . And sure enough it felt like all the others feel at there correct adjustment.agreed on 1/2 turn past zero. Always used that and no issues.
ya well i learned my lesson....i thought arp was in there but only on the heads,too bad i didnt read about this before the build....now i went over kill with the 7/16 but i shouldnt have any issues now at least...Too bad i just saw this thread now cause after reading your first post i knew what it was and as i read further i was looking to see if someone was gonna ask sure they are ARP studs cause my guess was they werent Ranger Joe nailed that. I broke a AFR rocker stud also in my 185s so after i looked it up i found lots of threads saying they broke them too, as much as i love my AFR heads im surpised they never have upgraded them studs yet. You should be fine now after i upgraded to ARP studs no more problems that was bout 10k miles ago.

thanks,ya sucks i over looked that!...but im going to give her a go later today or tomorrowyup i got that same lesson i didnt know AFR rocker studs were weak till i broke one then i did research, if i remember right there was a couple threads on corral about it. I have 25k on stroker now running real good last couple years its been just changing oil and couple little very minor things (knock knock on wood) BTW im running pro magnum rockers im pleased with and the ultras p m are even better.. good luck with her
