Dyno Sheet to Similar Engine
As stated in above post, you can look at estimate 1 and estimate 2 and see they are different engine builds. This shows Naylor Racing Engines/Pro Action Heads is nothing more than a scammer. The Brodix Head Hunter 395 Heads may make another 25-30 hp over the Dart Heads but as anyone knows you get approximately 1.5 hp for every cu in that equals 48 hp more out of a 632 cu in engine, so it is not hard to do the math and see the 600 cu in engine would not make as much hp as the 632

If you had put half the time into trying to solve the internal problem on the engine that you have put into all the lies and trying to SCAM everyone, the problem could have been solved already.
