780 diameter. Nice looking repair that will not affect the head at all.
It was properly welded and machined with the rest of the machine work. I bought this set of heads back in 2005 for an engine I was building up for a car to restore and subsequently after buying this set I found another set dated earlier that better fit the engine and used them in the engine build.
They are heavy, so will not be cheap to ship, I expect cost to be in the 50 range per head. Will work with buyer to find the best, safest and least expensive way to ship.
Be sure these heads fit your requirements before buying. 250 intake and I cannot offer any warranty on heads as the machine work was done back in all threads are good.
The head had been dropped and broke out a small chunk of casting in that area. Date codes are e145 and f165. Heads will use 2.
One head f165 has been repaired by the exhaust cross over area, shown in the last photo. These are now an extra set of heads that might as well find a new home on an engine. 880 exhaust valves. Heads have new guides, fresh seed valve grind, surfaced and pressure tested good.
Time to clear up some storage space, so I am selling off extra parts left over from restorations and parts buyouts that do not fit my requirements or needs, so watch for my other offers for these excess nos, new and used parts.
