Oil pan change?

Mike, I have that pan on my 340. So far 2 set of header hit the back corners of the sump. 1 set of cheap Hedmans and a set of $500 Hooker Super Comps. Im using it as an excuse to buy the TTI's i wanted but I would hate to see you try to swap in in the car to find out your headers no longer fit. I couldnt even beat the extra cleance in to teh header thats how bad they hit.

The other thing is you have to notch the K frame for the pan, not a big notch but it would be a pin with the motoe still bolted in.
