I didn't like the look's of the marine tex but been doing some searches it sound's like it increases bottom end is that right crab?

Creates a straight line for the intake charge to get to the transfer ports.

you have to use the epoxy to fill the water jacket voids in the cases as when you port the cases you break thro into that area . ive been running mine like yours for 3 years now and haven't had a problem so out that motor together and have some fun

Looks like regular case porting to me.
