"Decking" wet sleeve block

[Angelo Graham <a3graham@admmail.uwaterloo.ca>]

Hello List:
Have a question on decking or truing a TR2-4 wet sleeve block. Given the 
design of the wet sleeve engine, is it still a good idea to have the block 
to head mating surfaces machined true? I have done the steel rule test and 
the block surface on the perimeter of the block looks good. I have had the 
head machined true. The important sealing surfaces are the sleeves to head. 
Maybe I should have the sleeves machined "square"?
Any insights?

Thanks,
Angelo Graham
