Question for running roller cam

[Dubob]

Wanted to see what timing chain covers everyone with roller cams are running. Stock reinforced or???? for roller button. Pics appreciated. Thanks.

I can cheat and say 'stock'..'85-up had rollers, but I know you are probably asking about retro-fitting a roller cam into a BB/RB block.

My buddy has a roller cam in his RB and I believe it is the stock, stamped-steel cover

i've run a reinforced stock cover with an aluminum and a roller button in the pass. the supercharged motor now has a donovan gear drive with a roller button. i don't run the fuel pump on it so a made a 1/4" aluminum plate with an adjustable bolt and lock nut to adjust the cam end play.
