409 Tex....my heads are as built by the factory. Factory GM valves were 2-piece and should never be used. Good stainless valves are available now. Heads need to be checked for valve guide wear and touch up the seats as a minimum. Hot tank and mag also.
I have a 2x4 setup complete with fuel lines. Carbs are 3361-S front and 3804-S rear. Intake looks good. Also 425HP oil pan, the windage tray, harmonic balancer, timing cover, 925/926 HP 63-64 exhaust manifolds, water pump and crank pulleys. I also have a mint 63 3830814 block, std bore, no cracks, QB block and crank.
In the next couple of days, I will post all this in the Parts for Sale section.
