heads, 1950, chevy

I have a 1950, 235 with a water leak into the oil. The head-gasket doesn't seem like it fit correctly. I need to see what the head and head-gasket are supposed to look like.

I can't help much on what they look like but the old straight 6 cyl. head were bad about warping and cracking. If you pull it again you might want to take it to most any automotive machine shop and have them put a straight edge on the head and magnaflux it. Also if you haven't checked the torque specs I would sees like they were arounf 95 ft. lb. or so,

As far as I know the only other head you could have would be the 216 or you might have a 216 block with a 235 head and gut feeling is they won't interchange. GMC might have have had a pick up head that would kind of fit but not sure about that. Then you just might have the wrong gasket set.

Sam's right. 216 heads don't correctly fit 235. 235 is notorious foir cracking in the chambers. BUT... Just because it's cracked, doesn't necessarily mean it's leaking. Pressure-testing is called for. And yes, they DO warp quite badly.

The '50-'52 engine lists a different head gasket than the '53-'62, so that could also enter into this. Are you certain it's the original engine?

Take your head to a machine shop. Get it pressure tested and checked for straightness. Then buy a gasket from them as they know what you have.
Use a flashlight and lay it flat along the block look for a crack between the cylinders.

thank you all for your advice. I believe the machine shop is the best idea. thanks again

Whenever I have had a cylinder head off and the thing is all back together, I add a can of Solder Seal's Block Seal to the coolant. This ensures that any minor voids between parts will not be an issue, especially on old engines.
