well i now give up, broke another T&D rocker, i am at my wits end, each time right at 2/3 shift, last time i dropped shift rpm from 7000 to 6800 hoping to help, about 10/12 rockers last five years, maybe 30/50 runs on replacements, ex/int any clyinder does not matter, i guess i need to have a "expert" look at my valve train
540 cu stage IV heads .660 roller
on the good side went 8.92 151mph before 1st round and got my entry fee back


To tear up rockers like that you have to have valvetrain issues. PM me if you want it diagnosed.
