The Gaskets themselves look good to me and with the exit of the runners being so much under sized I do not see a issue once a normal port match is done but for what I posted about those right side pair of runners, as getting those right will take more work then just a port match!
Also a factor is these are cast to work with the peanut port heads too!
I hope your buddy understands that with amount of cid and today's other Manifolds for these oval port motors that there is no need for a 2-4bbl tunnel ram unles your into the eye candy of it ,or buzzing the motor up to the needed 8000+ rpm with that cid to use it!
Peanut port heads intake ports are wider than they are tall!
