My heads are stamped "022.101.372 G" . I've looked at the Porsche parts manual and can't find this number. Are these bus heads?

Many thanks!

I answered that question for you when you asked on March 9th ...

I know and thanks. I just wanted to confirm. I'll get the cam number tomorrow, but I'm pretty sure I'm running a 20. case with 2.3 pistons and cylinders with 1.7 heads on a stock cam with stock FI. No wonder it runs like !

Danke noch ein mal!

According the http://www.tunacan.net/t4/reference/cylhead.htm that part number is a bus 2.0 head.

Hmmm, actually, it doesn't say "bus" anywhere on that page ...

It's implied because is says 2.0 and it says small valves, which equates to bus 2.0. So, yes it does say "bus".

Will the 2.0 bus heads flow enough air to support a 2.0 Porsche case with 2.3 cylinders?

What size are the valves?

for that size you would want 46/38 with ports the same shape as the 2.0 liter porsche heads.

It looks like I'm running 37.5 x 33.

It also looks like the PO's claim of 2.3 wasn't correct. Its got 94mm cylinders on it.

Whoa, that's the second 'fake' big motor recently. Bummer.
