Hi there.

I have a 351 cleveland in a 71 convertible mustang without aircon. My question is changing headers.
I have a pretty good tool box, so i am comfortable with this side, but is there anything i need to know and what exactly is the skill level on a 1-10. 1 being putting oil in, 10 being rebuilding the gearbox, 4 being changing plugs etc.. 6 changing distributor etc..

Can you tell me the hrs required, any tips about easy of job and if i need to have special tools etc,

Thanks

David
