Thanks for the replies. I'm not exactly looking for a bunch more power at this point, this is not my current goal. My goal is to replace the stock rockers with something more stable and durable and just better all around than the 50 year old stamped type. I figure that 1.6's vs 1.5's would give me a bit more lift and duration@.050 without the negative drivability effects of a larger cam. Not looking to spend 2 or 3000 on heads until I'm ready for that. By that time the rest of my valvetrain should be decent stuff.
Don.
I'm with you, a modern rocker is going too feel like a fresh tune up. I also like indestructible, if your going too stick with the stealth head or update too a head that you can swap the same rocker gear over on too. I like the Comp Pro Magnum but they don't offer a 1.6 ratio but they are beefy, I fear aluminum rockers regardless of who makes them...
Me too. Agree the stamped style is marginal or weak for your application. Run hard, there is decent chance the pushrod will punch a hole in one.
I know you did not ask about rockers... but I think needle bearings on the rocker shaft, if that is what you are considering, is a reliability downgrade. The plain bearing works better and is more reliable at least in a moderate application like yours (and mine). If you really want aluminum, the Hughes would be better. I like steel and run Pro Magnums. The old style pro-magnums are good (bulletproof) up to about .6" lift and corresponding spring pressure. I believe the new ones have a bushing and can take more pressure/lift. My "old style" pro-magnums have 15k miles and track time and no problem at all.
