I need a set of good flowing 305 heads (s/r torquer-AFR)?. I would even take a good bare set of vette aluminums. I have a set of 92 350 centerbolt heads, (they have screw-in studs,manley guide plates, 2.02,1.60 SS valves, .575 lift valve springs, race porting and polishing has been done)for trade. I also have a 2-piece set of underdrive pulleys off my 91 Z28,and a stock TPI cam out of a 90 Iroc.?Trades anyone. Email me.

If you have the money and are going for a aftermarket cam then I would go with AFR 180cc they are expensive but well worth the $$$. The world porducts S/R just means stock replacement and would not make a big diffrence on your current setup I am getting the 180cc this Nov and they are going to be $1550 complete and shipped to my door. So if you have the money go for AFR but if not get the S/R Torquers and have them ported. But I think with the S/R's you can't run 1.6 RR with out changing the valve springs and on the AFR's you can. Also you are going to want the 1.94/1.60 vavles

Do you have a part number and some specs on the AFR heads??? Im also considering a good pair of heads for my 305tpi.. thanks!

 

The specs are: 180cc and 1.94/1.60 valves I also know that you can run 1.6 rocker w/ the springs that AFR gives you. The part # i am going with is 918(no heat riser)fully assembled for $1200. You also have to determine is you want the center bolt covers, L98(angle) plugs or straight, and if you want the temp sender unit drilled for you. I have all of these and the total is $1550 from a dealer for AFR.
