The ETA head has smaller intake and exhaust ports and is missing some oil passages. I believe the oil passages can be drilled out, but the mass flow restrictions would cripple an M20B25 engine. The mass flow restrictions would limit the effectiveness of the head when used on an M20B27. I don't know if the valves would clear the pistons.The car makes it possible, but the driver makes it happen.
