Hi, Not sure what this means
you don't need a double-throwdown camshaft and sewer-pipe heads.
I think your saying that the blower will make a good street motor out of stock heads and a mild cam.
The rotating assembly needs to be in good shape i.e
crank, ibeam rods & 8.1 c/r pistons for the 76cc heads. once this is built up you have a base for a street blown motor that will perform well at 5% underdriven.
not to get carried away with all the performance options avalible.
