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.
