Im not trying to piss off anyone or waste anyones time by any means. I cannot see buying a new set of heads and cutting them. If it was something making a lot more power than yes. Im trying to make do with what I have and buy as little as possible. I purchased a MSD pro billet distributor and 6AL-2 today and I hope that may help the 327 a little until I can get the 283 built. While I totally respect TechInspector opinion.....and Im sure he knows what he is talking about, I do not want to spend 1500-2000 on parts for something that may put out 300. This will not be my last build. Just trying to get something reliable so I can get the car painted and other things.
