Brad, I agree ... the oem kit is very nice for that price...and I have bought from Spike60 and will continue to do so. The one thing that I think the hyway has going for it is the plating... frankly its beautiful, AND its plated all the way up the combustion chamber. The oem has more even bevels on its ports though. I think if you are going to cut squish band, you want the oem cylinder. If you aren't, I'd still consider the hyway.
The one thing I ask is that IF people are going to buy AM, and they want to support my channel, to please use my link. If someone wants oem, I got nuthin to say if they buy from Spike60... I buy from him too!
Last I checked, this was my thread, my project, my comparison, my vids etc. Without being too self serving, I'm simply curious as to why he purchased elsewhere....thats all. If I am not putting for efforts in the right areas I'd like to know that. I've tried my best with my channel to be open and honest with people, so I expect the same back.
