anyone have drawings showing the ports/bolt patterns of the LX9 and LZ9 engines, that you would care to share? I'm wanting to see if it is possible to make a set of dual pattern header flanges for my turbo LX9 that are semi "future-proof"

it uploaded, but doesn't really help, the drawings I would need would be of the cylinder heads, not the deck."I am not what you so glibly call to be a civilized man.
