Engine, Head & Suspension needed

[Surbski]

Decided to have a little fun with my '69 510.

 

Looking for the following:

 

Engine: L22 or L20

 

Head: U67 or U60

 

Suspension: I guess everything I need for a 280 swap -- front assembly (struts/brakes) and back brakes?

 

Master cylinder from a 280 also?

 

I'm on a budget, but I'm also very serious too... so shoot me what you got...

 

Of course, if I find what I'm looking for I'll also have a low-mile L16 for sale now.
