When you run one of those smaller valves what kind of line do you run to and from it to keep it adjustable?

So you said it's a back up to the Bassett tee valve does that mean I don't really need to worry about putting it in or is it still a necessary piece of equipment with this set up?

So then if I want a ball valve to control how much water goes to the headers that goes before the tee valve correct? Or is that controlled by the gate on the pump?

Ok but where can I buy the water injection lines that go to the headers? And I wanted the adjustable valve train and lower cc heads to up my compression.

Hello all I am new to the site and also jet boats. I just recently bought a 79 20ft saber jet with a 460 in it and a berkely pump. The motor I was told had just been rebuilt... 3 trips on the water the bottom end went out cause the motor builder forgot to put the plugs in down in the lifter valley for the oil crossover... Oops. But I decided to build the motor because of this. I'm going to put SCJ heads on at 72cc roller rockers solid roller cam rpm air gap intake and forged pistons. I have an 800 cfm holley to fuel it. I'm looking to hit around 10.5\1compression. Best I have come up with is that I should be around 550 hp with this set up. I was wondering if anyone knew if my thoughts were correct about horsepower? And also if there is a possibility that I would have to do anything mg to my Berkeley 12 jf pump to make it handle that power? Any info helps!
