I just removed those annoying bolts as I need to replace the header gasket on driver's side, but I wanted to know if I should replace the bolts with the bolts that require the allan key. Have any of you ever used these bolts and if so, did you find it easy to access them and tigthen them?

Thanks,

Benny

allens are pretty good yeah, easier than trying to get a socket wall between the head and the primary tubes

sometimes

trick to do is hack off the end of an allen key and use a socket and extension then you will have all the room you need for the ratchet

good luck
