will 2.0L kombi heads fit on an oxyboxer wasser case?

what big port heads suit the beetle motor? seems daft to bore/stroke a 1600 out to 2000cc and expect the same valves and ports to cope...

Type 4 heads don't fit an oxyboxer engine, the push rod holes are in the wrong spot for starters.

Just run big valve beetle heads, O44's, or 040's with bigger valves. street eliminators can come with 44x38mm valves, thats bigger than the T4 valves
