243 heads is what you're after. And no, I sold it. Sorry, if I come across some I'll let you know. The 243s are slightly better performing due to better valves and smaller combustion chamber. They are the same as 799 truck heads, and the truck heads can usually be found very cheaply. If you do end up going 243s change the valve springs. There was a known issue with early 243 valve spring breaking. Better to be safe than sorry. You can get LS9 springs from lingenfelter racing for $70.
