DREMEL.... Make a slice in the screw head so that a screw driver can fit in there and just turn it out. I do all the time.

How do you do it on a head screw when you can't get to it?

You may be able to get in through the side of the head with a cut off wheel and cut the heads off of the screws.

i have had a few of these and usually you can squeeze some needle nose vise grips in there and turn a little at a time. depending on the cooling head fins and kind you might not bend or damage them much. just take your time. i had a grp that had one stripped a while ago and you would never know that i squeezed needle nose vise grips in there.

you can try using a hammer, and try to pound the screw driver down in there, sometimes it works, or let the engine run, so it gets hot, and then try it

That's a good idea. Unfortunately I have seen some where the screws are recessed so you can't get to them but it should work on most.

I use a Thorp Torx driver. It looks like a long,
one peice screw driver with a torx tip made
onto the end of the shaft. Pick one that is
just a hair bigger than the hex hole of the
screw and drive it into the screw head with
a few sharp taps of a small hammer. Apply
downward pressure as you break the screw
loose. Once it breaks loose it will turn out
the rest of the way with ease. If this fails,
you can try useing a small dab of JB Weld
on the tip of the driver. Allow enough time
for the epoxy to cure before trying to break
the screw loose. Good luck.

pull a hacksaw over the screw threads backwards usually it wont bite in but will grab the screw and turn it.

O.K., lets go one step further. There are drill bits
that are made with a left-twist, therefore you have
to use a a reversable drill for the bit to do its cutting.
These bits will catch the screw head and back the screw
out most of the time, before the head of the screw is
drilled all of the way off. The trouble is the fact that
left-twist drill bits are hard to find and they aren't made
very long in length. Screw extractors work the same way,
but I don't know of any the are skinny enough to fit down
the hole in the head to get to the screw.
The last resort would be to just drill the head of the damaged
screws off. If done properly, useing a drill press vice and drill
press, no damage would be done to the cooling head. There
would still be enough of the screw left sticking out of the block
to grab with pliers and turn out.

Dremel with a large cutoff wheel. Slip it between the fins and cut the heads of the screws off. Just had to do this on one of my motors.

Default head bolt removal

OK, this is how you get the head off.
Get a drill bit that is a little larger than the shaft of the head bolt and drill the head of the bolt off, the head of the bolt will pop off when you get deep enuf, and do this to both bolts and then when you can remove the head, the rest of the bolt will turn out with your hand. The head will still be usable when done.
Simple

Sure, just go into caveman mode, "TAKE HAMMA AND BEAT SH..T.
Get a sawsall and cut the whole damned cooling head off it.

Blow into the carburetor hard enough to pop the screws out of the cooling head

Both of these are spot on. bloke at my local hobby shop did the drilling method on my engine... it caused the tiniest amount of damage to my cooling head, but nothing to worry about...

The way i look at it.. you'd rather use a drill and risk damaging the cooling head.... than use a cutting disc and risk damaging the head button...

I had the same problem, had to cut the cooling head flush with the screws so I could slot the screw head to remove.
