Im going to go with the Screamin eagle Stage IV pro 103 kit. It comes with the pro twin 110+ cylinder heads. I can swap them out if I wanted to and pay a little more and get the MVR cnc ported heads. My question is are the pro twin 110+ heads cnc ported? And given the choice which would you choose and why. Total for the build, dyno and parts is $2,832.00 (they are credit back the SERT since i already have it). Would the MVR heads be a better choice? The kit comes with the SE 260 cam. Is that a good choice for cams. I dont do a lot of 2 up riding and when I do my wife weighs only 125

 

any info would help

 

i have the stage 4, ride 2 up all the time it pulls like a mule. hope this helps. ride safe

 

Absolutely, pay the little extra and get the MVA's. Make sure to get the 10.5 pistons and .030 head gaskets. The 110+ are not ported and if you look at the SE flow charts in the catalog on their website you will see why I think the MVA's are worth the 2 or 300 extra dollars. A guy did a flow test on a set of MVA's and they out flowed the chart by 10 at 650 to about 305 out of the box. A little overkill for a 103 but if you want to go bigger later they will work very very well and they still work very well in a 103 if you don't get too greedy on cam choice. And no ,do not ask "Should I get the Hurricanes" cause the answer is no. Get the 259e cams instead of the 260's if you can and also the get the tapered adjustable pushrods instead of the perfect fits in case you want to change cams down the line. Just what I have learned.

 

I just spoke to the service guy and he said he would put in the MVA heads instead and charge me an extra $200 for them. They were giving me 20% off on all parts. So its was worth it.
