Aluminum headed 318s?

Pretty simple build, we have built many similar engines but used magnum block for roller cam advantages. Search "explain quench" to read a good thread about what it is and why it works. Its nothing crazy or exotic, just common sense. I have always liked that build article because it used a much better cam design than most, proving with magnum heads excellent exhaust flow(for factory head) that you dont need more exhaust lift or duration with that head. Also a good example of why you dont want high volume oil pump! Just changing viscosity got them some extra ponies.
