hello...good question...I can get back with you soon on more detailed answer, but till then, try this for your knowledge-bolt together to see what you have from top of piston to top of block area-squench area.....
then you know how much to zero deck.... I think .100 should be ok but only a guess right now....
as far as head is concerned, what cam lift are you going to use? this will concern what can be done to piston and block....
as far as 194, there is more compression due to smaller chamber but to get to good flow you need to open chamber up-but if you open chambers alot you get get more compression and good flow-you have to be careful with 194 heads-some have core shift that can cause problems when you install hardened seats and bigger intake valves....Again, what is goal of engine? whats it main use? what rpm range do you need/want?.....
back to piston and head....you are on right track-i havent done this but have checked it out...now i can check it our some more- also measure your deck height-from flat on main bearing cap(block flat spot)-10.875 is standard-that is 10 & 7/8".....
I will get more info...hope this helps so far....
