Edelbrock heads

2 years ago I purchased my Eddy heads and I also ordered a set of arp bolts. While trying the bolts manually I noticed that the bolts next the pedestals that feed oil to the rocker shafts did not go thru. Looking thru the bolt holes I noticed that the area where the oil passage from the pedestal meets the bolt hole on both heads was restricted by what looked like a small ball of aluminun shavings protuding into the bolt holes. Since I live about 15 miles from the Edelbrock headquarters I took the heads to them and after 3 days I picked them up.
Obviously poor machining is the only explanation. Over all I think I was lucky If the restriction had been midway I would have never noticed and after installation I would have had lots of fun figuring out why oil wasn't getting to the rockers .
Moral- Add this to your check list. It only takes a few seconds to check...
