G'day mate

"The other bad rap was overheating because of the steam holes, WRONG they cooled great, the problem was putting the wrong head gasket on and COVERING the steam holes, then they would overheat."

Thanks Viking, I never had a cooling problem with a 400 block because I always paid attention to the steam holes, but others seem to have had. This explains it.

The # on my heads is 333882 = 350/400 heads. They also say F1276 or F1275 can't really tell. Motor should be a 75 or 76 350? Still don't know what it came out of though. Also, on the top passenger side of the block, is B? 49. the ? looks like a T or J? On the opposite side where the 3970010 is, there is also a GM with a 4 near it. I found another S on the block too. Does that mean anything?

Thanks for all the help!
