If your flexplate bolts were hitting the converter, how were you able to bolt the converter to the flexplate? The distance from the flexplate to the converter mounting pads is only 1/8" to 3/16" max. when converter is fully seated in the transmission. Anymore than 3/16" and shims are required between the flexplate and converter. There would have been a space when you went to bolt converter to flexplate. In other words, when you pulled converter up to the flexplate, the converter should have hit the head bolts before the converter mounting pads hit the flexplate.
I can see the witness marks on the converter pic.
One measurement you can do is with the torque converter fully seated in the transmission, measure from the face of the bellhousing to the converter mounting pads. Should be min. 1". Some say 1-1/8"
Another thing to check is that the hub of the converter fits into the crank. Also, next time your putting everything back together, you can spin the converter before bolting it to the flaxplate to check for any binding. Doesn't hurt to put a bit of grease on the hub of the converter before bolting it to the flexplate. The Flexplate does flex so the 1/8" to 3/16" is so the converter can move back and forth.
