    New oversized valves. !!!

    Have a ported stock valve gs 1100e head going on a 1260 engine I'm building. Prob use 370 lift webs
    11to1 comp 36-38 rs flats old style v&h pro pipe. Going to install oversized intakes and update valve job for 28.5 ss intake valves. How much more improvement if I do oversized exhaust valves. Would it really be worth it Just trying to budget. And already have the intakes will be a street strip bike 6 over cal fab old model swingarm 5.5 inch gsxr wheel with 180
    tire in an 1983 gs1100 ES.

    You also need bronze guides with cams that big. The stock guides are too tall & the retainers will hit the tops of the guides at full lift. You should also go to 24mm exhaust valves.
