I want to take my welded E0 head in to check for cracks, one head guy said not to bother...Went ahead and got two more D7 heads from the yard---but for the life of me---I can't see anything that looks like a crack or warp on my E0 head. So, a friend of mine said to do a few things before I take it in and risk losing money on a cracked head.
1) Block off the intake manifold at the carb inlet (rubber seal).
2) Turn the head upside down and level it.
3) Pour diesel down the intake runners until valve bowls are full.
4) Let it sit over night and check in the morning. (If full the inlet section is not cracked).
5) If it is empty then it is cracked, so replace the diesel fuel with gas, then sprinkle the head intakes with talcum powder and it will pull it to the crack. For the exhaust side he said to do the same thing.
