  I doubt it, but strange things do happen;
    The only reason I call it a '52, is it's stamped 23.12.52, so probably a '53.  I started with a frame (actually circa '55/6?- BA7S 1919*), a tank and half a guard that I found in the local 'Gabba wrecker, and grafted the engine/tranny from Sandgate, and we're all on the other side of the planet  *eek*.

 Was it the post you were after? I just pasted your words in the 'search' ; first failed attempt was 'this post' so I tried 'search entire forum' ..about 30 seconds *smile*

Looks like it could be, while I've got your attention, did you ever have grief from a solid copper head gasket. I cannot get this one to seal, either that or oil is finding its way into the barrels from elsewhere, but where *dunno* *dunno*

There is two drain holes at the front of the gasket that need sealant on them, could this be it?

??

 have you run a straight-edge across both faces in many directions ?  Even placing the head on the barrels maybe the studs done down (finger-tight) and a bright light on the opposite side (sunlight) can work- or put the head on with out a gasket or studs, and some engineers blue-stuff

Ok I'll give them a try, not sure about the drain holes tho, the previous gasket was the same pattern and gave no trouble. Thanks I'll keep you posted 👍

Hi,
Have you annealed the gasket?
Remove any rough edges around the bolt holes and make sure there is some clearance around them
Check cylinder and head for flatness
Make sure the head bolts are in good condition, free to screw all the way into the cylinder threads
The head bolt washers distort and cause binding on the bolt heads, make sure the bolt head faces are flat (spot face them)
Use a little anti seize paste under the bolt heads and on the threads
A little bit of sealer (hylomar) around the oil drain holes and the pushrod tunnel wont hurt
