Unfortunately, FE hydraulic roller lifters are done by about 6000. Plus there's only so much horsepower to be had by a naturally aspirated, Edelbrock headed, pump gas, hydraulic roller'd FE....(that was a mouth full)

As for all aluminum engines and setting lash, I start with a cold spec of about .010" under hot spec. Easy to check on the dyno and I can run through them in less than 10 minutes.
