Just being on the safe side, I would like to ask a question about the location of an aftermarket aluminium header. Mine is on and I had to essentially dent it so that it wouldn't touch the oil pan. Now that I put the motor back in, I noticed that it (including the flex collector) is very close to the oil pan. Just wanted to check to see if anyone else has had this experience and if I needed to rig up some kind of heat shield. It doesn't touch...just close.
Thanks,
Ivin
