Vavle stem height....

I guess i just paid for parts and machining. I certainly didn't pay for them to "blueprint" it. Although, I just assumed that when I had them install hardened seats and do a valve job, that it would be done the right way. I mean, if you are replacing the valve seat, wouldn't it go without saying that the newly installed seats would be machined to match the existing valve seats? I'm shocked that you would have to pay extra for it to be done the right way. Don't get me wrong, this guy wasn't particularly cheap, and has a decent reputaion in the area - I wasn't trying to take any short cuts.

Regardless, it's my fault for not noticing it when I picked up the engine. My biggest concern is if this varience can be rectified with the adjustment in the new rockers. I mean I know it CAN be done, but does it throw off the rocker geometry such that it will afect the performance of a street engine?
