No squish,no value what so ever you don't get what you think you're going to get. An the good reviews are people who don't know what they are talking about 😡

Does not increase compression. Basically more cooling fins and poor mating surface and poorly tapped. Junk.

I haven't really tried it out yet just got it in the mail but I've already noticed one difference between it and an older style they're exactly the same except for some reason it look like they modified the squish gap on the head I'm not really sure if I like it.

For a $32 head, it is outstanding. You cant expect NASA quality on a $30 casting. I had to run a thread chaser through the plug hole, but other then that, It is more then worth the money. If you cant handle little issues like this ,you really should not be changing a head.

Had to resurface mating area, spark plug threads need cleaning, bike runs much better thanks to all the cooling fins

The gasket surface was not machined flat and was rough cast a good seal just isn’t going to happen head had a gritty residue all over it likely from the manufacture I just sent it back and went with a CNC machined billet head

It was the cheapest head, but don’t let that fool you. This head works great and did not explode like one of the reviews said. It gives you loads of low end torque and I think it looks better that the other high compression heads with the rounded off edges. Would definitely buy again if I get another bike.

It came straight out of the casting sand I needed to polish and mill it before application to the engine

Way better than the stock head! - This is the second one of these heads that I have purchased and they are great performance for the price. I have the other one on a bike that I ride almost daily and have over 500 km on this setup and I will buy more for other projects as long as they are available! - I've spent a lot more on CNC heads that don't perform any better.

This is a great head at a good price. As far as the women who claim it "blew up" her engine if you know anything about these parts you know a head does not "blow up " your mill. It's an alloy head and has great heat desipatation. I have not calibrated what change there is to compresion but these parts can be "decked" to your needs super product

Mine was packaged fine, but still came very slightly chipped in a few spots, so not PERFECT, but it still looks and feels very well made. I am having issues getting the spark plug screwed in all the way - I can't get it to 'bottom-out' - the threads get VERY tight early on, at least for me. Using an NGK quality plug. Don't understand that issue, other than less than perfect machining. BUT the bike still runs fine... I just can't tell how well the plug is actually in, as it mounts very deep in the head, and of course, the threads are rough.
