Blocking the heat crossover, IN the head.

I'm telling you for a FACT I have tested it and you can't find 1 HP. NOT 1. You are pissing away your time. But don't tell me it works if you haven't had flow bench and dyno time to back it up.

I decided to work a Sunday one time and a pontiac "guru that wrenched at the shop I was at spent the entire day filling his ports. Went to the flow But being the hard boiled book reader he was, he spent the money to test on the dyno and found zero. Nothing. I asked him if he liked working for zero.


You can spend way less time and make gains than doing this deal

Some guys only learn by doing. Just post VERIFIED results.
