mac90, the great part of this re mod aussie design is firstly we have the original ada u.s.a. design head kit that did cost a whopping $250 we then modified and tested atleast 6 cylinders before we got the correct combination that worked better than the original ada, [thanks to ozminimotos ] for there great cylinders. another mod we did was increase the compression ratio from the ada 13 to 1 to our 15 to 1 ratio. due to the massive size of the boost port only the 10 mm piston pin sized pistons will work due to ring guide spacings.
