Well, the photos seemed pretty relevant to the OPs question. Especially since I would guess he's looking to run an LA intake on a 1970 340.
As for core shift, yeah great. Some are way off, supposedly some are not, which means some may be even worse than what I got. So, quality control is for crap and there may be some out there that are worse than what I had.
I go to look at a new car, I open one door and it falls off, I don't care whether the door doesn't fall off of a different car of the same model, I'm not buying it.
Is it worth the crapshoot when most people just want to bolt it on? Hell no.
As I said several times, I did compare and do probably still have photos of the Magnum intake alignment (someplace). Runners and ports on the Magnum were also larger than the Pro Products, and for sure didn't have the misalignment issues that the Pro Products exhibited.
