Don't want to hijack this thread, but for a mildly modified 340, are roller rockers worth the cost. My 340 is right at 375 HP, and I was thinking about buying a set of Comp rollers. However, I don't want to spend a lot of money for only a small gain.
I know you're not asking me but i got (0) performance gain when i put my roller rockers on, some 15 years ago. but have lived well threw two 340s and now on a Hyd roller cammed 408.
