Even though I am going to the Dark Side (IO-360) for expediency for the time

being I still want to use a Rotary eventually.........I am seriously thinking about 

P porting my 13B and would like to know how your 20B is holding up particularly 

at your port insert junction using the machined plates and sealant.........Have you 

had any major problems with leaks so far ?.........I have a pair of plates from Paul

that have the "O" rings and if I recall correctly your plates were prior to the ones 

with "O" rings..........I am curious whether you had any major problems when you

were smoothing and putting the radius the "TIG" welds........On the same question

did the "TIG" welding seem to cause any warping of the rotor hsg steel liner ?........
