Super Jet Best head?

[Andersschroder]

What is the very best girdled head available for the superjet. I.m looking for reliability first and foremost. Doesnt matter what it costs.

Thrust is the best head out right now. Looks the best too.

They all do the same job. I have 3 ada heads and one Thrust. The Thrust feels and looks better made.

There is also a blowsion one piece head that just came out. Wouldnt one expect that to improve on years of experience from other heads?

Also the cold fusion one looks pretty cool with built in domes

I would not want a one piece head. 35 mL domes should've given me 180 psi but instead they gave me 210, so I have 37 mL domes and 170 pounds of compression. This all changed when I scored a piston . Maybe it's just my luck but that's how it went for me. I don't see an advantage of a one piece head, But there is a definite advantag to interchangeable domes

I dont get it. How can you expect 180 but instead you got 210. Thats a huge difference?

Based on the ada chart. Have different jetting than FPP suggests too. Props, domes, carb tuning, you arent always going to match the charts exactly, and once you start boring the cylinders and changing pistons it can change slightly. I matched the charts on a stock bore and piston, but not after a bore with pro-x pistons. Just got different domes not a whole new head. Ski runs great.

2 stroke heads are just lumps of metal. They don't move or flow anything, so I don't see any one being better then the other besides having changeable domes.

Any head is good head. Why am I the only one that knows that!

My only experience is with ADA heads but the Thrust heads look very well made. Either one will give you many years of service.

I thought the same thing. There's no such thing as a bad head, it's just good or great.
