I have 6 out and 2 to go....

The two remaining are (round headed) allen-head bolts. They're holding the damper plate to the flywheel, so I suspect they've been torqued pretty good and may have loctite on them too. The other 6 came out pretty easily with steady, centered pressure. But these two rounded the allen recepticle and now the wrench just goes round and round. :(

They're in close quarters, so a brute-force big-ol-vicegrip approach isn't (and didn't) work because the grip of the vicegrips bumps against things. The bolts themselves, are small, about a 3/4" long, 5/32" shaft diameter and about a 3/8" round head with a 4MM allen fitting in the center.

So, what are the tricks? Heat? mini-vicegrips? chisel? file a face on the head to create a surface for a cresent wrench? Easyouts?

I really don't want to end up having to drill them out at the risk of then having to replace the flywheel when I screw up the drill alignment and damage the receiving threads. I'm on my belly as I do this work, reaching below the the level of the cabin sole into the bilge.

They're out!!! Due in large amount to all of your helpful advice. The trick that did the trick - hammering a slightly larger than appropriate torx socket into the rounded allen-hole. A little leverage and I was on my way.

Thanks, all!

(and SWW914 - I know those CV bolts well, my other "sailboat" is a 30yr old 911SC Targa -funny!)
