Hi All,
Just acquired a set of crusty old Weiand heads for an 8BA. At first I thought I had a couple of busted off spark plugs that someone could not get out. I did the acetone/ATF soak and they came out fine. But, it was then I noticed that those two were the larger thread, 7/8" socket old sized plugs that someone had used to put in as I guess they ruined the later smaller threads. So, now I am pondering the best way to fix this mess. Should I drill all of the other holes out for the bigger old style plugs? Or, I just found where there are adapters that can be screwed in to use later plugs.

Kinda related, but not. Even though the heads are for an 8BA, the ears for the oil filter can are not on and not even cast originally. There is no need for any deep reaching plugs like we usually read about on here for Offy heads. The area for the plugs is only about 5/8". Did they make 8BA heads specifically for racing applications where one might not be interested in bolting on the oil filter? Thanks in advance.
