Talking crap??
I will remember you said that when I see you!
Those KB pistons have a very generous amount of valve relef. Remember the pistons are down the bores when the valves are fully open. Or at least they should be!
Yes .528 valve lift is plenty for your little engine but how long is it at that lift??
Plus where as a Chrysler cam will give you a lot of duration to get that lift a decent modern cam (and there are a few others apart from Hughes these days) will give you the same lift with a FASTER RATE (this is much more important than just max lift) but with much smaller duration so you get good vacuum, torque, idle quality etc. All the things that make a car more fun to DRIVE on the street.
