I have 2 pair of cylinder heads for sale. The first pair are both 243 and have yellow springs. The second pair are a 243 and a 799 combination with regular springs. Both sets will have to be re-built and completely gone through. Price for 1 pair is $410 shipped. OBO.

You can run a 243 and a 799 at the same time. There are Corvettes that came from the factory with 243/799 combinations. I bought them like that to run them as a combo, and be different. $410 obo. Shipped.

243 vs. 799 heads talked to GM research tonight.
I talked to Bob (Gohard777) and Mr. X. There is no difference between the two heads. The numbers tell what original mold the casting came from. 243 mold was done at GM Research, the 799 mold is used by other vendors. The same vendor will have 243 and 799 molds. The numbers are just a GM system for when the mold was made. If a head had a problem it helps them track down where the problem started. The only difference between the heads is production variance. Case closed. Thanks to Bob and Mr. X. Mr. X machined the first 243 heads himself at GM Research.
