the hieght on the boss/351c cover is fine i have 1 motor with roller cam 671 lift and 1.70 rocker and it doesn't hit the covers. close ,REAL close but fine. if you go into 700+ lift you will need the spacers and those look like crap!

Yep, Got it, I see the 69 is slightly taller and has an even radius as opposed to the 70 where the radius gets tighter at the top.  I'll dig up some plain blue 70's and see what I can do to mod them and get them close.  Great pictures of the 69 cover conversion.  This should be a fun project to help me sharpen my tig welding skills.

Forrest... have a look at this website. It's a fellow by the name of Paul who did an excellent job documenting his work. If I bookmarked it right, it should be the page on the valve covers and exactly what you are about to do.

   Chris ,
   A lot depends on the type of rocker and valve cover gasket used. For instance I used a Crower stainless with .775 actual lift at the retainer with lash and had no clearance issues. You could also use the Felpro steel laminated gasket for a little more room.

    The breather tubes in the bookmarked section are too low on the cover itself. The original '70/71 breathers were centered on the cover. and a small cover was welded on the inside to inhibit oil from blowing out.

   Forrest , I might be talked out of my T/A covers. PM me if you don't want to go through modifying stockers.
