Roller Rockers

273 rockers best 4 U
or b3 shim kit with roller tip rockers

a note on stock rockers
some have a hole in pushrod cup and some do not
depends on if oil through the pushrod or not
do not get it wrong or you get smoked rockers
hint- hole always works
get the pushrod length right and stock rockers work fine at that lift- we had to race with them for years
but get your rocker arm geometry right even with stock rockers
