Here are pics of the built up head by mpgmike. The head was ported, deshrouded, #4 coolant mod through the frost plug, 2 Singh's grooves added, heat coated chamber, valves, and exhaust runners. Valves where back cut, 3 angle, polished. Conical valves where used with a 30 thou shim and PT lifters as well. Head CCed at 46. The complete head, disassembled, was cryo treated. Flow #s and more info can be found in the May 18, and July entries on the main page.
