Thanks again for this outstanding product, everything so far on it is just perfect!

Piece of art!! The shape of the intake and exhaust channels are perfect. Proud to be a dealer of your products in the Netherlands.

Way better than anything out there. Very throttle responsive with more top end.

Got my heads today, they are AMAZING!!

I’ve been working on Harley-Davidson engines about 40 years. I bought your set of cylinders and heads - some of the best work I’ve ever seen!!!

Very impressed with the Shovel heads. Much admiration from every one.

I got heads and cylinders in Japan. Super nice, thanks!

I'm so impressed with those billet heads, they're AWESOME!
