Block and Head Crack Repair in FW Area

[gogrannygo]

1928 Tudor - just got bad news from mechanic. He was going to bore the block for new pistons, and found a crack in the exhaust port in the block back towards the cylinder and one in the head from the water jacket hole to the head bolt hole. Anyone know where we can get it repaired around Fort Worth? Any idea on what the cost should be? He said it should be no problem to repair since it is small at this point. Appreciate your help. GGG
