Let me say it this way. You can’t put enough money into a 302 head to make it a TF head. It will never be that. If you like a dick measuring contest to prove you can sit at the porting bench and kill yourself just to show you are the smartest guy on the block then go ahead. Stupid is stupid and spending any more than 500 bucks on those heads is dumb. So I don’t care how much power you think you can make with them, I know I can make more with a TF head. Or a Speed Master head. And not spend the time or the money doing it.
