Re: Cam spec help! (TR x-post)

The other thing that clearances can play with is time on the seat. This is
especially important for the exhaust valve, which has a lot of heat to pass
into the head (and thus to the water jacket). If it doesn't spend enough time
on the seat, it's more likely to get burned.

Cam profiles are black magic, as far as I'm concerned. I buy from a reputable
manufacturer and follow their recommendations.
