Just shopping around on ideas for my new TPI (89 B2L/L98 350 TPI), and I thought it might be nice to upgrade to a set of timing gears so I can nix the timing chain stretch problem and never worry again. Seem there's is a difference between roller-cams and non-roller-cams for the gears though. I read somewhere that we might all have rollers, but I wanted to check with you guys... Input?

Any TPI motor built after mid 1987 have roller cams.
