what do the heads flow? how many CFM at what valve lifts? while you are there,get the intake manifold flow tested.Are you custom building the headers? what will you use as a CR? How many RPM will the engine be engineered for? Are you using shaft rocker arms? Do you have a carb yet?
also the raised runner heads are expensive by the time you finish all the machine work.Are those pistons compatable with the small cc heads?
none of this combination makes sense to me?what is the application?These parts are getting on the exotic side,so please explain the situation?
Its a lot of money to see what it can do to a dyno,,,,
