My joy quickly turned to anguish as coolant spewed from the radiator. I have learned a lot from all the post and you guys have saved me lot of frustration so once again I come to you with questions.
I think I have a restriction in the coolant passages. I running a 53 head on a 60 block and Im not sure I got the right head gasket, Im thinking the gasket is blocking the passages because the head is full of coolant and the petcock on the left side of the block is dry. Am I thinking right or am I missing something Help me out guys once again
I work & work & Work and I still cant afford it!

If the block has not been cleaned professionally in a tank, the petcock area is probably plugged. This doesn't normally present a problem. Your coolant surge may be the result of an air bubble. Also if the thermostat is stuck, coolant will come out the overflow as the motor warms. You could try running it without the thermostat first, to see if all works well without it. | | |
