roller rockers vs modified
i know the roller rockers are supposed to be better, both performance wise and for durability of the engine, but how big is the difference? worth the $100 difference they are advertised for? im lookin to do this next spring so im starting to look in the for sale section to find used ones first but i dont wanna pass up a great deal on regular 1.9's if i try to hold out for rr's anybody had both? opinions on each?
thanks!
