Hi David,
If you are going to break a head bolt, that's the one to 
break.  No need to do any removal or repair.  Please 
reread my post on the subject of head attachment.  You 
DON'T need the outer row at all.  Do NOT torque the other 
bolts tighter...66 lb ft is enough even with steel gaskets 
and only 10 bolts to a side.  It is more important that 
the bolts be torqued in proper sequence and in stages as I 
so carefully outlined.   To torque the  bolts tigher only 
risks distorting the block face.  Check the block face for 
flatness.  It the block face is distorted, it should be 
removed and planed.

  Andrew didn't have room in his Echo to take the heads 
back with him so they will be shipped Tuesday.  Remember 
the SD1 heads use plugs of different reach from the P6B 
heads.  Do not try to use P6B valves, valve springs or 
valve spring retainers on the SD1 heads.  These parts do 
not interchange, but the assembled heads I am sending you 
will interchange with the P6B heads as complete 
assemblies.  No need to change pushrods or anything else.

How gummed up was the inside of the engine?

Hope you don't have to pull it out.
