Well said, not that I have anywhere the knowlegde of blykins on engines. With stock lifters and standard valve train components, 150 /400 would be minium but once again I have limited knowledge only my own experience, I would think 170 /450, but hey every engine is different. I do like the idea of keeping it below 5500 rpm, just use a rev limiter. With heavier spring pressures I would use the redline break-in additive, you have some serious forces on your rocker arms, pushrods etc. Set your lash about 1/4 turn that way if they float no damage.
I am sure I will get flamed but some of the best lifters on the market are standard ford racing. About $140 for set of 8.

It will be a little lighter on the torque, but the midrange and upper end horsepower will be very fun.
