need help with timing chain selection

I have a '91 L98 and need a new timing chain. What I need to know is how can I tell if one will work on a roller engine if it's not specified? I saw one set for rollers but it said it's only for rollers up to '90, so do I need to find a set for rollers 91+?

What's the difference between double roller and true roller?

Would I need a set with three key ways or 9? Or either? Which is preferable and what are the keys for?

PS: are cloyes sets any good? i see them in performance catalogs but they're cheap so i dunno. What's a good set for $40-50?

as long as u dont switch out cams and go edelbrock and brand should be fine. get a double roller. if u get a new cam and go edelbrock they bone u and make u get their timing chain. any others wont be correct timing with an edelbrock cam. trust me i found out the hard way. when i swapped cams i went through 3 different brands before i read the instructions for the cam and found out i had to have an edelbrock one. plus it was like 80 bucks

I'm a little partial to the single roller sets, with the larger true roller chains (with real bearings) and a lot larger chain pitch. The weight is virtually the same as a double roller set and they are quite a bit stronger.

So you're saying that with an Edelbrock cam you need to install an edelbrock timing chain? Maybe you just solved a weird little problem my friend has. He put in an Edelbrock RPM and some (I forget the brand) timing chain. Now his timing mark is way off the tab. We got it running perfect but have no clue what the actual timing is.
