Hey!! Starting early, combine ready to go so...... What kind of head would you recommend for an 09 800 XP? Had a SLP on my Sons 07 and seemed to work great. Any suggestions?
I put the RK tek drop in kit with a 13.5:1 head, a set of boysen reeds and got Deano at mad Motorsports to do the power valve mod, and my 09 summit pulled like a train! Would recommend doing that any day!
I have an engine tech 14:1 head on my 2010. Made a HUGE difference. The biggest difference I have ever noticed from an aftermarket part. Had to add 3.1 grams to each arm to get the revs where they needed to be. Id say it added some power!
Im on the fence about doing a trygstad 872 so I would probably sell it if you were interested.
