Looking at a fast by gast head. Ported and oversize valves milled 3 thou. I have a 1507 at 13 to 1 compression. Everything is done to my motor. Carillo rods heavy duty case and head studs ape springs. I don't think I missed anything in my build except getting my head done. This is a street bike with occasional track use. I will also be sending nitrous to it this year. I guess my questions are does fast by gast do good head work and will the head be an asset shooting nitrous. Or is it just a waste of money. Thank you.
