And my first choice was:
" What type of street driving ( hours, miles per year) if it's going to be limited I'd go solid roller. If guite a bit I'd still go solid roller and use Isky Red Zone lifters"
As of yet has the OP stated what he plans on doing with it, how many miles per year etc.?
There are quite a few solid rollers running around on the street and more than a few do the Power Tour every year. I know a guy who did it with the Isky Red Zones with over 1,400 miles. Pulled them out and inspected them and put them back in.
Do you know the mechanical abilities of the poster? Do you know if whether or not he has the ability to pull an intake manifold and swap out standard roller lifters after some numbers of miles or hours?
Yes we are entiltled to our own opinions, you take a mechanical flat tappet and I'll take a mechanical roller and stomp it in the ground

to each their own.
