Hello all, new to here, looking for someone kind enough to give a little wisdom and hopoefully pictures of a bowl blend, exhaust cleanup,guide work, and how do I deshroud and make sure i dont hit the seats! and valves if installed? And how much of a valve nick is too muchto affect heating or airflow?? I really am on a strick budject, no give, gotsta get done soon. Daily driver, winters coming.
I surely cant afford a valve job ( reason for the 187's!) going on flat top 350 S-10( sorry guys, but were all family, right?) comp single 268 HI EN., 600 holley. any advice about working these heads, and assembly of heads to intake and whatnot would be very appreciated!! ( summit gaskets ok for quench?)
Also, anyone happen to have a diagram so I can wire my fuel cell to my 87 dash?
Thanks much, zjh9601

You should check out the TBI forum on this board since 305 TBI motors are what those swirl port heads came on stock.
