Intake design for stock appearing class and needed a winter project

Track to begin with, I have AFR gauge to get it close and keep an eye on it for going lean. The good thing is it will SMOKE if it has a vacuum leak. It will pull in crankcase air if anything. I’m confident I can make it not leak vacuum. I plan to coat all the seams with splashzone on the exterior. Also make a sheetmetal cover to keep hot oil off it and catch any pieces that might come off and could cause damage to the cam or lifters. Also plan to pin with a screw the big blocks sealing the original upper tracts. I’m losing about 3-4”’s of runner length, but I really can’t help it. I can’t use the side of the vertical plenum like a traditional single plane does. No room without changing the outer manifold shape around the choke well and heat cross over well. If it picks up anything significant and If it runs with steady AFR, doesn’t lose mph and It doesn’t show distribution issues on the plugs, it would probably find its way on a chassis dyno before I change anything else.
