Check AFR's web site for a base plug reccomendation, as for the rocker arms, check the geometry as it wipes across the head of the valve.

Sometimes, aftermarket head guys use chevy 1.6 rockers to design the heads, Ford's geometry is slightly different (I know this sounds wierd, but I had Canfield fax me some instructions for thier cylinder heads once, and they reccomended the use of Crane gold race chevy rocker arms because thats what they used to develop the head).

Anywhosit, just make sure it works right and you have plenty of clearence on the piston side of things and your set.
