Just picked up an evo 9 long block with a spun rod bearing, looking at doing a big head build and was wondering what the rocker arm ratio is? same on intake as exhaust?

Getting various information, don't want to reassemble the head again just to measure it.

Thanks,
Jon

 

ok, I will reassemble heads and post my results.

 

1.72 rocker arm ratio. The checking process below.
