I had my rockers re sufaced at Delta Camshaft , I think it was like $2-3 a piece. They have been a great company to deal with , my dad and I have had maybe 10 cams including some really wierd 30's era cars (pierce arrows , packards that sorta thing) here is thier web site Delta Camshaft
EDIT~ JUN also makes cams for L series motors , cant remember what wierd catalog I was looking in for that one......
