Do I need a Double roller with H/C?
On the other hand I would reccomend changing the chain while you are in there due to slack that might be in the chain from useage... and just general wear and tear that the chain goes through.
I will be doing a set of stage 2 heads hopefully soon and will be doing a new timing chain. I was going to do the yella terra rockers, but do not have the money to spend on them.
You don't have to do a double roller, you could just go with the single Jwis chain that Thunder sells and use your stock sprockets. If you have a ASP pulley, there is a good chance it will hit the oil pump with a double roller, and I think the Jwis is as strong as they come IMO...

At the very least, go with the upgraded timing chain. They're not really all that $.
Good luck.
