I sent these questions to the Comp Cams tech support and never got a reply. Maybe one of you guys around here can help.
There's a roller lifter retrofit kit available from Comp Cams that consists basicly of the stock 5.0 lifter guide assembly (Comp Cams #31-1000). However the instructions say this can only be installed when the engine block has the two bosses cast into the lifter valley like the roller blocks do, and you will need a camshaft with reduced base circle in order to keep the lifters from coming to far out of the old blocks shorter lifter bores.
Comp Cams also sells these roller lifters with link bars:

As far as I understand these will work with normal base circle roller camshafts in the non-roller engine blocks. Can anyone confirm that?
