Kevin, as close as I can tell, with all these parts of mine assembled, we get 13 3/4" from the intake surface on the head, to the upper part of the taper on the shock tower, and 10 1/2" from the plenum bolt flange to the lower tapered part of the shock tower...
With those parts I sent you to mock up awhile back, can you figure these aprox measurements now that I've given a figure of 13 3/4 from the heads intake flange surface, to the shock tower?
If I mucked these measurements up, please advise and I'll try again for you....
