Have you done it?
Because I’m pretty sure he won’t have to pull the headers to drop the pan. The road race pan has all of its kick outs below the headers. It will be harder to access the bolts, but if the steering link is dropped the oil pan can be dropped out.
And the engine doesn’t need to come out to pull the headers either. I’ve removed and replaced the Doug’s on my 340 in the car with the engine still on the mounts. Even with the road race oil pan in place. Personally, I’d leave the pan alone and drop the headers again. They’re the easier part to modify, and you don’t have to mess with resealing the pan. Yeah pulling the headers is a pain, but I don’t see how it’s avoidable.
Even if he had to do all that to drop the pan, he’s gonna have to do it anyway after he holes the pan with that spoon. Better to do it before the pan is damaged than after.
