Which Gen 5 double roller timing set?
 

I'm looking for a timing set for my gen 5, 525SC rebuild and after some research it looks like the following are recommended:

1) Roll master CS2040 -$122
2) Howard's 94309. $97
3) Cloyes. ??? $???
4) MT recommend one from compettitive but no part number

I'm looking for one that does not require clearancing the block and would work with this cover

Also is there a way to verify if I need a shorter timing set from line honing/boring or just a standard?
