So not to beat a dead horse here but i have been doing tons of research. Heres where i'm at... I picked up a set of 441 heads for dirt cheap (couldn't pass them up). Now is it worth the money to completely go through them, bigger valves, back cut the valves, mild port and polish work, ss swirl polished valves, valve job, guides done yada yada yada... or should I just pick
these up? I'm easily going to spend that on these heads... so what do you guys think, where is my money best spent here? Thanks
