Differences between TSP 5.3 heads What are the differences between the older 5.3 heads and TSP's new design. I know their website said they feature smaller ports but how much smaller are they and what other differences are their?

The "new" design has clearance cut under the valve covers for after-market rocker arms...no more need to grind your heads to clear those rockers! Also, with our newest CNC machine we are able to tweak the port slightly and squeezed 3-5cfm extra out of both the intake and exhaust!
