milled/shaved heads on 1100?
Will this help my raider out any? Do you know where I can get a stock head that has been shaved/milled for the raider 1100?

It should help acceleration and maybe a little on top too.
I just happen to have a stock 1100 head and new gasket that I would sell.

Well if any of you know the story of me and my dad he finally spilled it all out last week and told me he shaved the heads on it...So I dont know how to do that and I'm not going to ask him to. I just want to buy one that has already been milled and put her on and not tell him.

Some of the shops will not cut the older 1100 and 1200 heads Pro-tec for one will not I sent my 1200 to groupk and had it cut I have two one on the GP and one on the SUV they do liven em up.

Code man, it will increase the punch out of the hole, but with out crazy compression it helps mostly the acceleration,you must go to premium gas also if you run 150 psi or more, I always do it for the complete package, it is a worth while investment, about 65.00 in most shops here, cut .010 for every 10 psi you want, but make sure you know what your REAL compression is to start, Big (RAIDER)Mark will have a Riva milled , 150psi stock head for sale after while, but not real soon, get a cheap, used NON milled one and get it cut , that way you can just swap it on weekend, real easy, you will need a new head gasket and depending if the top cover comes with it, maybe a top cover gasket.....

ok, Im really gonna do this than
One more question, just to be sure...
What do you think would be faster/what would you take if you wanted a faster raider...
Mine: nujet impeller, 5 degree nozzle, cut intake grate, pro-tec shortie....some other small stuff
Dad's: nujet impeller, 5 degree nozzle, cut intake grate, milled/shaved heads?
He didn't have the shortie ride plate and i dont have the heads...what would be faster on smooth water on top end?
thanks for all your guys help!

Unless he has done other things to it, they should be pretty close, I would personally take yours and modify, then there is no guessing, abiout how it was setup , you will know exactly what you have in it, the head swap is easy, the shorty is a must....I have not had any good speeds with the Nu-jet,,no offense, have you tried a solas 13/17 or 13/18 with mostly stock you wont believe how hard that thing will pull, Island Racing can re-pitch a 14/20 for you, the root angle helps from the 14/20..maybe you can get a loaner and try it out......Nu-jet was known for its vacuum signal, .to keep the ski planted, not for top end...too much overlap on the blades...

I havnt tried a solas but the my old man has. He tried it and sent it back because he did not like it. He said it would run too high of rpms so he went with the nujet and had the best results.
I dont know anybody who could mill the heads for me here.
