Well I got my magnaflux kit in the mail and checked the 416 heads and they appear to be crack free. I will be sourcing a used 350 engine maybe this weekend. Do tear down check the rotating assembly over and go from there. I haven't decided if I want to have larger valves installed or just port them. i don't know if with still having the factory TPI on there he will benefit from the larger valves. But then again I guess a 52mm throttle body would help the intake breath some more...

Does anyone know if you can cut the factory seats larger with just the sioux stone cutters? I have used these before for doing valve jobs but it doesn't seem like they would cut enough material to use to cut the seat larger. If not Ill just have my machinist do it and charge my buddy the extra cost to have 1.94"x1.60" valves installed.
