i'm using the hughes roller rockers on my 340 and 360/426 stroker , so far no problems , think the kit cost me 6 0r 7 hundred a few years ago , might be more today .took the shop hours to measure and custom make the shims , but worth the extra $$ ALSO USING 1.6 rockers on both engines offset on the strocker
took the intake and heads off today lifters and rockers are in new condition , no wear at all 1.6 cryo rockers and the drop in roller lifters , 7000 miles so far
