Default Tire Shredder Heads

Hey guys. Does anyone out there know if the heads that come in the "Stage 5 Tire Shredder Kit" are any different/better than the factory heads that came on 110 CVO's? If so, how are they different? I have been trying to find info on them and have been having a hard time.

If you do indeed have a 110 cvo you would be wasteing your money on a new set of heads. Take that money and have yours worked by a good porter and you'll have even better flow numbers and more power....

There is a huge diference between a cvo110 head and the tire shredder 110 heads.
Cvo 110 uses a larger combustion chamber and larger valves, similar to the mva heads. Because of the larger combustion chamber it takes domed pistons to create higher compression.

The 110 tire shredder kit comes with factory ported 103 heads. They flow better than a factory 103 head but not as good as a set ported by one of the many builder on this forum.

Considering I'm getting the tire shredder kit over the winter, I want to say that sucks to hear. However, that kit will put me at the limit of my stock crank as it is so I guess it's not a problem. My dealer printed off a dyno sheet of one they installed this year putting out 118 hp and 128 tq. They say my setup should get close to that, but who knows. From what I've read dyno sheets are about as trusted as opinions.....

After talking with Steve @ GMR and Frank @ Dragos, I decided to just buy the 110 CI drop-in Jug and piston kit. I bought the Dragos Stage 2.5 Heads and H-Pipe exhaust. I took all my goodies to Steve @ GMR he did my install and tune with the GMR 577 cam and GMR Compensaver and new SE Compensater The compression was set at 10.3

122 HP and 128 TQ, over a 100 #'s TQ from below 2000 to almost 5800 RPM

Instant on TQ and pulls hard all the way out to redline

IMO...there are much better combinations than the Stage 5 tire shredder kit.

Call, Hillside, GMR, Dragos or any of the good builders and have them design a setup for you.

Now, all of them are going to want to sell you their 107 Kit instead of the 110 drop-in kit, but for me and my need for lots of low end TQ, to pull my heave trike, I wanted and needed as many CI's as I could afford. I just politely told them this is what I want to do, now what have you got that will help me.

Put together right, this 110 CI drop-in kit will make you grin like a Hyena

I don't doubt you one bit. That same thought has been bugging me since I set my mind on getting the whole kit. The only thing is that I am doing the install and my dealer is doing the dyno. They know this kit pretty well and I dont want to get in too far over my head mixing parts. I sometimes wonder if they would do a half *** job dyno tuning it for me if I mixed and matched components just to try and prove a point. I think I will stick to the kit as is since in a few years I hope to drop in a much larger brand new motor anyway.

Like I have said, peak numbers don't concern me. I want big torque early that carries all the way through.

JMHO, but I think you stick with the Stage V kit or, as an alternative, purchase just the cylinders/pistons and work with a head porter to help select a cam set and have your heads ported to match up with the cam set. You can have your throttle body bored as well.

The 110 kits seem to be working out, holding up and making decent power. It is however, common knowledge that head porting and aftermarket cams can enhance the performance of any motor compared to one of the HD kit offerings.

Why would you buy the ported heads in the kit then trade them to fuel Moto? You would be better off just buying only the 110 cylinders and pistons then using the heads and cams of your choice.
