After my daily lurkings of the tex. I thought I'd make my interest for the week Big Valve Heads.

In the states, there's a bunch of guys breaching 200whp* (now we know they always make more) but. They all have a heap of different head builders.

My question is; who is possible of doing this work? The regular vw crowd?

Or perhaps breaking out to companies such as, trick and mansweato (800hp+ n/a v8. After all the head is just a head.

Anyone have any thoughts?
