AL, it would have to be pretty thin. If I were running a blanket I'd just put a larger/deeper radius in the cut in the pan. The two tubes you see in the photo actually have had some work done to them as I didn't cut the 408 pan as much. The 434 had to have a 340 pan so I made the cut bigger. My headers were uncoated too, I cut the flanges, worked the tubes and welded in a O2 bung before sending them out. Another thing is the collectors are made to go on with a slight tilt up. I didn't catch it and welded my bung on, and built the exhaust, The d/s collector would drag on my trailer when loading or unloading. It finally dawned what I had done and I turned it over and redid the d/s exhaust, but I can no longer use the bung because it's to close to the header. The p/s I left alone as it didn't drag and I think if it was installed correctly the exhaust would be hard to get by the transmission cross member. On a pure race car it may not matter though.
