VR-200’s…… AGAIN…….
Just thinking this over, the only reliable , can't lie is to take a known sorted out, legal race car, like a record setting stock class car, and put those heads on a good shortblock with a great level of prep and let er rip. Then look at weather corrections, tire type, trans, etc . And see just how well the heads do. The problem remains of just how well joe average customer will use those heads though. Case in point. Me. In a course of 24 years, using 440-1 heads, i moved from about 725 hp to 926 hp as i went through different levels of prep and porting, shortblock, compression change, i got more and more out of those original castings. And a good friend is closer to 1,000 hp with the same head. So i get thier reluctance to post anything but track times.
