ok, here is the deal. i blew a head gasket on my Stang. since i dont have much money, i want to rework the E7's. my plans are port and polishing, 3 angle valve job, and bigger valves and milled .010". now what valve size would be good? i will be running the stock cam with adjustable 1.7's. if i dont go with the bigger valves, will i have piston to valve clearence problems? if i do go with the bigger valves will i have clearence issues there also? how do you "clay" the pistons?
oh yeah, just to let you know, i know somebody who will do the machine work for cheap.
