Kuah...all I did was machine the block and assemble your cylinder heads. I personally did not assemble your block. I no longer work for Raymac so you can say what you want about them. As I said to Don a week ago or so as I know you two speak is that I will warranty that engine even though I didn't assemble it as I did machine it. If you have any issues or anything you can share with me that was wrong based on its assembly please email me.
