What sort of improvement should I expect from an RKt Head in a 03 700 xcsp at sea level.

Is it worth the installation..?

also PM him .he did a lot of testing

if you can measure the deck to piston height , you stand to gain 3~5 hp in the midrange and 2~4 hp on top. Also you have a head that has better cooling and less likely to have DET problems. The head I have runs good has none of the issues some have posted, Bonz has the same head also... Mine is set for sealevel and 93 fuel..... If you can run good fuel he can set you up with a combo that will run really hard!

Thanks for the direction XC

Answered all my questions plus a couple I didn't even think of.

Much appreciated
