It was apart before, by me, and I am sure I didn't use locktite. It was 12 years ago, head gaskets (hahaha). None of the other 10 have locktite on them.
I think my best/cheapest bet is to sawzall the rockers, get a couple new ones (7 bucks a piece), use the blue wrench and some vise grips.
I have rounded off bolts before, not this badly, and not recessed.
Biggest issue with the rounded bolt head extractors is that none of them seem to have a 9mm one. I have an older (3 years?) Craftsman set and it skips 9 (8, 10, 11, 12, 13, 14, 16), as does the Horrible Freight one. The Horrible Freight one looks higher quality than my Craftsman one.
