Kunar, you are about on the dot. However, the amount of work to modify the head only is astronomical. It much easier to modify the block, which then only requires a hole to be drilled and tapped for an oil line on the head.if you really want to do this I can find a link for you to a guy who has the entire build documented. If you are going to do this for power, don't bother. Its no more powerful than a stock 4 plug head is capable, actually a little less at high valve lifts. And the cost of cams, pistons and machine work alone is going to run you close to $1500
