Hey guys...feel a bit like a noob, but i need a little help from all my truck enthusiasts out there. SITUATION: im restoring my 82 short bed chevy...i've taken out the ole stock 305 and am replacing it with a rebuilt '94 vortec motor bored .20 over(vortec heads), edelbrock intake with a 770 Holley carb. i'm now at the stage of purchasing a set of headers and thats where you guys may be able to help me out...will i be purchasing headers for a 94 model motor? or an 82 model chevy?? i think i've looked at so many pair of headers i've simply confused myself but...perhaps you guys can be of help. also, what brand have you guys had luck with/would opt to stay away from? Shortys or full-length?? your help is much appreciated..
