i have a p72 head.. crower stage 2 street strip camshafts..crower titanium retainers and duel springs.... crower 1mm over stainless steel valves... was wondering what do you guys think this head could rev up to?

 

i would be more concerned with what the bottom end can rev up to since its the oen that will fail first.

 

yes you are very true... however the oem block will just be temporary as i am getting a b18a with darton sleeved closed top 84mm bore...so 2.0 and then im also turboing this

i was just curious as a tempory thing how much you think it is safe to rev to with a oem block/built head setup like that

 

if its just temp, i wouldent go much past stock
