Roller cam opinions

I have a BB street car with a solid roller and a SB street-strip car with the same, both are doing great.
The BB has about 3000 miles on it and the SB has 9500 street miles and about 65 1/4 mile passes.
I have done Hot Rod Drag week two times, driven to Las Vegas and back once from Phx. and drive the SB car to work a fair amount.
The lifters have never been rebuilt .
Brian at IMM built the SB and the lifters are from Comp.
But as stated above you really should have very good rocker arms and valve springs.
If your heads have not been ported you may want to spend the money there first.
