I did add a strip on the backside of the timing cover to close the gap and to create the flange that is vague on the kit part. Also added a strip to the front edge of the intake manifold to close the gap.
With some effort the high rise manifold from the Revell T-bolt could be made to fit the Moebius block. The T-Bolt engine is a 427 wedge but the port spacing looks close enough, at least for me it is.
Wonder if any of these 3D printed parts (intake manifolds, valve covers, headers) fit the Moebius block?

Harold Bradford, the owner and artist behind Historic Racing Miniatures shared with me his build of this kit , needless to say it is very impressive. I'll be following your build Matt.
