Alright guys I am finally getting around to building my 300. I want to do a blowthrough just for the fact that I havent got the $ skill or patience to run a megasquirt. I started with an 82 f100 motor with 88k on it. I yanked the head knocked the valves out of it and "ported" it which more or less consisted of knocking the slag out of the chambers. Should I gasket match the head or is that a no no. I plan on using an offy single plane. The valve stems were pretty worn from the seals so while I'm at it I'm going to put new stainless valves in and a 3 angle job and use a positive type seal versus the factory umbrella type. I haven't decided on a carb yet and want to know what everyone's opinion is (besides going efi). Head studs and stronger valvesprings are in the works as well. And the age old question of turbo size is another question I have. I'm not planning on going over board with boost (~10psi). I have been offered a holder hx35 off of an early 12v Cummins but I think it may be a bit large. Any opinions and advice would be greatly appreciated.
