302 heads

yeah theyre crazy high. ive read that porting sticky on here a couple of times. I think I can do it. im not afraid to try .but what ever is best bang for the buck, if I do end up running across a 360 on the cheap some how (ive found em around here for $400-$600 and theyre smog motors seems high to me for a core but I may be wrong anyone that knows feel free to chime in, im always open to suggestions and thoughts) anyway, are there any necessary changes or parts I need to change from 318 to 360 like different mounts, flexplate, convertor etc.
