After seeing this post i just went out and picked some up from my local fastenal ~2 minutes from my house... its been on my to-do list... i did not get the drilled ones however because the original bolts are 5/8" in length and these are easier had, undrilled. i am thinking of using a lock washer as opposed to drilling them. im not against safety wire! all for it actually, i also figure Lycoming and continental engines exhaust manifolds are held on with lockwashers and nuts so that should work here aswell.
the most important thing is to torque to spec and re-torque after a few heatcycles... the socket cap screws allow easy access while the 12-point was a nightmare with the exhaust wrap.... actually now that i think of it safety wire could hinder an allen wrench from seating to torque check. either way. good job, and excellent recommendation! should have been this way from the start.
