| identifying heads (S or R..)
Is there an easy way to identify what type of head is fitted to an engine?
I've got a set of low mileage 2002 heads that cost me less than the price of a pair of rockers, and I want to know how to check if they're S or R heads?
I know they're not E's as they don't have the "step".
But
are the stamp marks on the top significant?
Do I whip out the vernier and measure the valves?
Can I check the cam without taking it out???
Cheers
