Need parts for chevy 4.3 fuel injection 262 motor

[montekels86]

looking for some parts n advice on my chevy 4.3 fuel injection 262 engine

im rebuilding it but i cant seem to find some parts for it because most companys dont make them im looking for headers, and the intake manifold and valve covers in chrome dosent have to be crazy expensive not looking to race just to drive if anybody knows a website that i can get these parts from

I've got a mpfi manifold/injector set complete with fuel rails/regulator/injectors/injector harnesses. It's brand new from mercmarine. Only thing you'd need to do is swap out the throttle body if you don't have one (which are cheap).

Tell me what color you want and I'll paint it, can't chrome it (cuz the upper half is plastic):

200$ even, shipping cost is added onto that:
