1.5 or 1.6 rockers on magnum heads

Dartman if I remember right your running the Magnum EQ heads aren't you? If so they flow good all the way through 550 lift so unless it's a clearance issue the 1.6's will help. If the cam you like is already .550 lift or higher there might be a problem with clearance. After looking over the small block geometry I see the 1.6's rockers straighten it out slightly so there's a little more benefit to them than just the added lift. Not a huge amount but some. Just something to think about.
