I am looking for a set of the 64cc iron 5.7 TPI ( IROC or GTA ) heads . What casting # are they . And what will a used set cost .

 

083

What the seller will accept.... who knows? Depends on the seller... but being stock heads, expect $100-200.

 

Ok thanks for the info . Now I will try and find a set locally . There was a Junk yard that had some GTA 5.7 TPI cars . So the #14101083 are the 64cc 5.7 heads . How are the 305 heads #14101081 ? What size valves and chambers are they ? I know I can find a set off them . Any info on the TPI 305 Heads ?

 

081s are the 305 TPI heads of that era. 58cc chambers, 1.84/1.50 valves. Very similar in many ways to the 083 heads except for the ports, valves and chambers being smaller.

 

This junk yard near my house had all kinds of F-Body TPI cars two years ago . Last summer all the cars were gone! Looking for a set of 083s in IL .

 

got a set of 081 complete, 083 bare heads make an offer ,you pay shipping,later jimmy

 

The ports on the 081s are the same size as the 083s.

 

I want the 083s with the larger 1/94 intake valves 64cc chambers . I have a set of 305 #601 heads all done up screw in studs guide plates 55 cc . But they did them with 1.84 S/S intake valves . Don't want to sink more cash in them . May run them on a 327 build . The 083 Heads are for a 350 build .

 

youre welcome ,tango,later

 

Still looking for a set of 083 heads in IL for local pick up .
