I know very little about the type 4 engine, but members of my club keep referring to these 'magic' cilinder heads
They have various stages of heads for 2.4 up to 2.9 type 4 engines and a 2.0 head that is supposed to make 160 reliable hp
For the 2.9 they claim a reliable 220 hp
Any of you care to comment?
