So I have a 06 LTR and I'm getting the head work done as well as plus size valves, and the company doing my valves said there getting the same amount of flow with the stock valves as they would plus size... They said plus size is 2cfm more then stock and it's not worth the money, does this sound right to anyone???

My quad will be running 497 big bore,PC3,Dasa exhaust,Webb stage 2 cams and Dasa intake!

Help please!!! Thanks!

My builder does pro level builds , and doesn't believe its necessary for the oversize valves.

Really?? That's good news thanks for your quick reply

Builders that know how to get power out of LTRs recommend at least +1 exhaust valves on stock bore builds.

So my next question is can the head work be done so well that the bigger valves wouldn't make a difference? I have asked the place to give me the CFM flow so I can compare with local shops.... Does anyone have any specs on what's out there CFM wise for plus size set ups??
