i'm going to be building a motor for nitrous...a lot of it.

now obviously the block is going to be sleeved with forged rods n pistons to withstand the pressure. but what about the head? will anything help keep the heads somewhat cool and not heat up the valves too much. i've heard of people spraying enough to lock up the valves because of all the heat. is this a concern?

btw...150-200 shot on a b18c1

my friends car was running a 120 with the stock b16 bottom end and sock head hit a 12.1

 

thanks for the reply...anyone ever run closer to 200 shot with no problems?
