Big tube header vs small tube header on a stroker

My son had my firend laser cut a flange out using a gasket for a pattern. He then fitted them to the heads around the pushrods. Then he welded them up with the air filter to match.

The covers are just blanks he ordered and fitted to our motor using the flange he made. The breather bungs were welded in by us . Its hard to find covers with out the holes and then they are left breather in the front , And the right breather in the back.

Because we wanted both breathers in the front for the evac-system we had to make the covers ourselves

Here is a picture of the bottom of the valve cover flange getting fitted to the push rods and intake, He also milled and fitted up a aluminum timing cover. Most all of the fabbed parts on the car were made in house.

He is making some cool parts for the new car he and I are building.
