As you may know, on RSR head, valve angle was reduced to an included angle of 55°45' with an exhaust angle of 30°15' from vertical and an intake angle of 25°30' from vertical.
I do not yet know the 2.7 valve angles, as I can’t find any references in any books.
That depends on what cams you will use and your current piston-to-valve clearance.

For "S" cams, nothing needs to be done.
