This was all just a thought exercise. Probably never going to see the light of day in my Z.

Another common swap is a Folvo, a Volvo head on a Ford 2.3L
I want a Racing Dynamics / Callaway DOHC head for my E30!
I seem to remember (can't find it right now) a bit about where a Volvo racing team, turned an 8 valve head into a 16 valve head (to fit some racing series rules) instead of just casting a multi valve head.... seem to remember the heads cost in excess of $100,000 EACH
In reply to oldeskewltoy:
Some of the Scandinavian rallyists are nuts that way. Rules say must have stock head casting but unlimited mods allowed.
Of course that is just the nature of restricted racing. IIRC the BTCC teams were spending more on cylinder heads than Formula 1, because they had to start with OE castings and after development time, they'd get heads that would crack after one race (porting deep into headbolt columns already weakened by heavy angle milling) or they would have to go through three or four castings before they got one that had core shift in the right place.
I like the Walkinshaw 5-cyl Volvo head. Rules said the intake port outline must be the same height above the deck as stock. They didn't say you couldn't mill the flange a few cm inwards, so they did that so they would have to make the runner more vertical in order to be legal...
The things restricted racing makes racers do is totally counter to the premise of the rule.
And if you are not willing to read between the lines in the rule book, you will be beat.
I could tell you some really cool stories from Formula Vee and Quarter Midget racing, but then I'd have to kill you.
