Hot headed.

Recently a brand new racing-head with impressive flow charts came out of the woods. To be more precise it's one or another Swedish pine forest.

A close up of the JPM. Out of the box these puppies should outflow most of the aftermarket heads, and with some more work the could almost make it to the major league run by Pauter and the likes. It's a Type 1 head, but it will fit your Type 4 as well.

And this is the machinists own car. It's clear what these heads do to your car, let alone your neighbours's.
