  1. Yep need correct spring pressure, I did my conversion for more choice of cams and easy valve adjustment, but it involves welding cam face and re machine, heads were more readily available then, not sure id do it now days.

    Ray always said to me when I was playing on tracks its serviceable item be prepared to replace.:(

  2. Panos you won't be able to use airbox with dot head and your have to beat fuel tank in to get carbs to clear.

    The dot head great on stock engine great for increasing cc the chamber fair bit smaller, the raised compression with down draft and port shape gives good gains but with 1216 its not going to work, there would not be alot left of the piston to get compression somewhere near, there are ways but you got look at big picture and look and what your compromising for those gains.
