Default Water in Cylinders

I have a problem with my 74 Formula with a 455, 30thou bore and TRW Lumpy top pistons, it has around 10 3/4 compression and i have been driving it for the last 15 years, around 20 thousand miles when on the weekend the temperature started to go through the roof while parking, I have a sender in the intake and another in the head, the one in the head went to 230 deg. while the inlet read 150 deg. i thought it might be a jammed thermostat but when I tried to restart it, it locked up. I pulled the plugs and found a few cylinders full of water on both sides. I have taken the heads off and the bores look fine, the head gaskets are not blown and the results from the machine shop say the heads are not cracked. any ideas?? I have also written this in the Street section.
Cheers.

What head gaskets are you using? And what 2 cylinders had water in them? The gasket could be the culprit without being obviously blown out. 230 is too hot for one of these old motors. Not like todays motor that are designed to run there.

Felpro gaskets and it was more than two, it was 5, 7 and 8, it climbed to 230 when it was off.

Gotcha, then 230 in that situation isnt unheard of. What heads are you using?

He got this posted up in the street section first , so I guess he does not like the reply's to it there!

Actually he posted in both sections (Street Section 1st) well before he got any responses. My thought would be he wanted a variety of opinions on what was causing his problems. No harm in that.
