These heads are in perfect shape but I’ve just decided to go another route on my engine build. They are AFR (Air Flow Research) 190cc heads with a 68cc combustion chamber for a small block chevy. They come with screw in studs, guide plates, installed valve springs (sorry, don’t have any info on the springs) and valves. Valve size should be 2.02/1.6. The heads don’t have any cracks or any problems with them. I’d suggest a 3 angle valve job and a resurfacing and you’d be good to go. They are for perimeter bolt valve covers and standard early style intake bolt pattern. I was going to use this for a 383 build but plans have changed. These heads have been discontinued by AFR within the last few years and have been replaced by the 180cc and 195cc heads. When new these went for +/$1,400 so I’d like to get $950 for them or best reasonable offer (I am open to negotiation). Heads are located in Pleasant Hill, CA (east bay area) and are available for pick up or possible delivery/partial delivery in the greater bay area (PM me to work out details). I will ship but buyer must arrange and pay for shipping and packaging (figure about +/-80lbs for the set). I’m in 94523 zip. I’ve got LOTS of pictures of these so if you’re interested PM me and I’ll send ‘em to you.
