another header leak

had aset of the cheap os one time, same prob, i took them off and and took a flat file and held it flat and worked the head flanges just a little to true them up, it shows where the high and lows are, then cut the piece that connect the tubes tobether with a hacksaw or recip saw, one cut in between cylinders in case its not all true it will have some give to adjust true, then i put a small bead of high temp rtv on the head area and smoothed it out , then the header side, and then put the copper gasket in there and tightened it up a little at a time to make it pull even , or you can smooth it on the gasket itself, on the collector iran a good wide bead on it to connect to pipes and tightened it up, in my case it worked pretty good at both places and i was happy, but no two cars ae the same, check to see if a tube may be hiiting something not letting it pull up good and seal, i think i had to use a ball pin on mine a little, nothing bad, just a little, hope this helps, good luck:blob:
