Re: the bigger piston squirters.
On my own build I'm going with a Ceramic Thermal Barrier coating on the piston crown to reduce heat loading the stock Motronic pistons and have abraded the undersides, to increase the surface cooling area exposed to the piston squirters. Me thinks that this should be enough insurance for my target (350 to 400 HP window) build.

Didnt know that about the 3.2 valves
As far as the squirters go- if your goin for 350-400 you should be fine
