Custom 42mm intake, and 36mm exhaust valves, with custom retainers and locks are here for our 4000hp dragracing #billet #Hel engine! Lets take a quick look.
The exhaust valve size is especially critical at extreme power levels. In addition to low mass for high rpm capability.
Almost everything is custom when this heavily redesigning a Nissan GT-R R35 VR38DETT engine!
