Just got my 587 heads back from the machine shop for my mild 360. They are mid
Seventys castings with 3 angle valve job and new springs, guides, and hardened seats.
I noticed in the exhaust ports a lump of metal not found in the earlier j heads. Can I
Remove these and grind them smooth with the rest of the port?
