I've been looking for a suitable way to increase compression without resorting to dome-top pistons (which I understand can disturb flame propagation during combustion), and have recently been reading about "angle milling." Prior to this, I hadn't known there was an alternative to the standard fare, straight across milling of the heads. It is my understanding that the maximum amount of material that can safely be removed from Pontiac heads is around .060", when regular milling is employed. However, does anyone know how much a Pontiac head can be "angle milled"? I am curious as to whether or not a significantly greater amount of reduction in combustion chamber volume can be achieved with this process compared with standard milling alone.
