I've recently bought a 239ci ebu code Y-block to replace the dead flathead in my 53 customline and I need to know,

1)   Will any Y-block oil pan fit this early engine? I need oil pan with main bulk of oil pan at front of engine, 

2)   Are all Y exhaust manifolds interchangeable with this engine?

3)   Are full gasket kits available for 239's as I'm having trouble tracking one down?

Thanks for your time Lee (london, england)
