BRISCA F2 Stockcars run with 90 thou off the head. Thats about as much as you can get off without serious pinking probs on 4 star or breaking into the
plug holes.
Take much off and you'll struggle with 95RON fuel. But assuming you are going to run Super Unleaded / Genuine 4 star or with an additive then a
"fast road" engine would normally have about 40 thou off the std Pinto head.
