Do you need a double roller timing chain with 105# valve springs?



Can you?

Yes.

Do you need to?

Not with 105's.

Quick answer for a kinda vague situation...factory cam or rockers as well?
 
Dave @ TEP had 130's with a stock chain/dampner and whatever cam he was runnin if that makes you feel any better about it, ha.
 


So your saying my topswap setup with a xp cam and #105s will work just fine with my stock timing chain/dampner. My timing chain/dampner have 90k on them.
