Nice job Chees 
Thats more or less how I was planning to make my IM. As long as the bellmouths are well matched and radiussed in the plenum I think this manifold could perform pretty well. There is of course the possibility you will need to better match tapering to the real flow needs of each cylinder, but I suggest you do the testing with the new EM fitted. Different EM layouts can make substantial differences of VE among cylinders, so you better match the IM to your definitive EM.
As Tommy say, measure EGTs on each exhaust runner to figure it out.

P.S. Being very busy lately too, so I apologize for any late or missing answer to PMs and/or posts. Testing my "stroker" at the moment....

Will report soon
