This is the 4th time I am changing the heads on my boat have some good dyno time. The sr20 the port volume is to big the low end and mid range would be gone or I would of bought them but ended up going with the big duke sweet 16*.
BB2+ boat plenty of power to plane off than I went to a 351 oval port boat would plane off ok. Put the 383HH on it would not plane off on calm water. But the power went up may be 40 or so. Think sr20 is 440cc and the big dukes is 415 but the runner is longer.
Shooting for 1050-1075 but it will be on 100LL aviation gas.

Worked on a set of the 18* race low port heads had to weld the tops of the ports up to keep the exhaust from leaking out. Hold the gasket on the head and you could see light above it. Don't know how they sold this.

I'm talking typical Brodix's guys. It's all generic talk. Brodix get's a low rap a lot....and it's just from the bolt on and go crowd. No head hunter stuff, no cnc stuff......

The only way I would not buy CNC heads if they where not going on my motor!

Curtis is very good!

I don't know the man just thought his products looked impressive.

If you can afford him Tommy Slawko does some amazing heads. But you have to pay for it.
