LPP header clearance to heater box?
Has anyone had issues with the #8 primary hitting or being extremely close to the bottom edge of the heater box? I just installed the engine/k-member back in my car with the headers already bolted to the engine, and am having this problem. They're either touching or they're so close you could barely stick a piece of paper between them. Anyone else had this issue? If so, how did you fix it?

I must have the worst fitting set of LPPs ever. I ground the hell out of the pass side k-member to get clearance, had about 1/8-1/4" when everything was assembled on the k-member before the body was placed back on top and bolted up. Could get my hand between the driver's side header and k-member. Now that the motor/trans/k-member is all bolted to the body, the #8 is practically touching the heater box (can fit a couple sheets of paper between them), the #8 is touching the k-member in two places, and the driver's side header is almost touching the k-member now where there used to be 1"+ clearance. I'm gonna throw these things in the dumpster soon! lol

I dunno, it's all stock stuff, and the motor mounts are new stock-replacement rubber. If there's any adjustment in the factory stuff I'll give it a shot. Good suggestion.

I have the same problem with my LPP's in my 97. I also had to do a bit of K-member cutting, grinding to bolt the headers up.
My #8 primary was touching and melted a hole in my heater box during tuning/dyno. I have the motor out right now doing some other work, and heated up the primary where it was touching, dented it in to clear, and I'll be wrapping the header as well to prevent any further damage.
But...I have AFR heads. Wonder if there's ANY difference in the dimensional location of the exhaust primaries in relation to the motor versus stock heads.

These are ported stock heads. They were milled maybe .008" to clean them up, that's it.
Brand new rubber trans mount too btw.

Ok, here's the best pics I could get of the clearance problems as well as some shots showing the mounts and overall fitment of the engine/trans in the car.

Driver's Side: (Used to be able to stick my hand between that pipe and the k-member before I bolted everything to the body)
Passenger's Side: (Notice I've already ground down the pinch weld quite a bit as well as flattened the curve higher up)
