    Default Wet Header Research?

    Have a 22 ft Commander.. BBC... Looking into wet headers that will be safe under the engine cover. Been looking and asking about several different brands and it seems one guy says they run perfect and the other says dont ... reversion problems.. It seem like the anti reversion cam is important so assuming I have the right cam...

    Emi??

    Lighting?



    are the two that seem the best price point... anyone willing to offer their experience with either?

    Thanks

    I've had lightnings in two boats now and have had no problems with reversion. Now I have changed a cam in my latest boat to make sure that I'm safe stay around 250 degrees of duration at .050 and you should be ok. Internal and external flappers never hurt either. I also had my last set of headers made with longer collectors so that the water would have to travel a lot further than the stand length headers. I'd say the key though would be the duration in the cam. Call up Jan @ Lightning if you have any questions he has an in house dyno and has tested lots of stuff. He'll be happy to help you out with specifics on a cam for you.

    Thank you.... Appreciate the info. Do have the double flappers, Long Collectors might be an issue as my motor sits a bit low and there is decking from the stringer outward to the gunnel.... Will call Lightning and get a cam recommendation.. Will have to call Marine Power and see what cam is in this motor stock... My guess is I'll be ok to run for this season then the motor comes out to be made a bit more playful.

    Thanks Again.
