d4b Flathead Cylinder head

​This d4b cylinder head is a copy of the Thomas flathead that I used to produce about 10 years ago.  It has 7:1 compression, uses long reach 14mm spark plugs, like the Champion RC12YC or the RN12YC.   I now have remade it in a style that will allow the use of the 1932 B water pump. New replacement water pumps can be found elsewhere on this site.  This head has many improvements over the previous head.  It has lots of structural advantages internally that make for a much stronger head where the original Thomas head didn’t have thick enough material to help reduce the possibility of blown head gaskets.   In particular the area between cylinders 1 & 2 and cylinders 3 & 4 have been beef up with an internal rib about 1 inch tall to stiffen up the head.  It is also produced with a 9/16 inch thick deck.  This head also has a great squish area directly above the piston,  note no piston relief.  This causes lots of turbulence in the chamber and better fuel burn.   The clearance between the head and the block is only the thickness of the head gasket, therefore, pistons must not come up out of the cylinder bores more than .030,,,,,,,more than this and there could be piston to head contact……This must be fixed during engine assembly by checking and machining the piston tops down to the correct clearance.  Also note that the water pump is O-ring sealed.  Any standard B cylinder head gasket will work with this head.  Comes ready to install.
