710 VALVE RACING SPRINGS Testimonials At T-Man Performance, our goal is to produce the highest quality cylinder head on the market and to do that we have to use the highest quality components, that’s why we’ve elected to use AV&V valve springs. Maintain their consistency and reliability even with the higher lift cams and higher revving motors that T-Man is known for. Three quick examples include my personal bike with over 250 wide open dyno pulls during training seminars, and two of our client’s cycles, one with 16 000 miles and the other with 20 000 miles on the springs, all three were within 1% of the original specifications on tear down. AV&V springs provide the quality that we trust for our performance products.
