HEADS........

valves = 194/150


are those 305 or 350 ??????

dude on CL is selling a set of heads for a "sbc TBI out of a 92 pickup" for pretty cheap, and i happen to (still) need heads for my 91 RS, i just don't know if what he's selling is for the 350 TBI they put in the trucks, or a 305 tbi that they may have also put in trucks ..........

idk i really don't know much at all about the motors from 1985-1992.

thanks in advance. I emailed the guy, and asked if they were 305 or 350, but, i just want to make sure he doesn't call me and tell me they are for a 305 just to sell them to someone who doesn't know any better haha...

better safe than sorry.

 

Ask him for the casting numbers, only way to tell. Hopefully they are the same. Then look them up here:

Of course they could have been changed in any way - larger valves, skimmed, hogged out etc.

 

probably 305 heads
