I know he is. I have purchased a few of his projects and I have a few more to get including that gasket. I was referring more to the outlining of that gasket to match up with the head and IM. I have RC PnP IM but it's not a single running. I know it it said to be limited because of the design and more even if you convert it to single runners (I can be wrong). I just want to make the right decision of porting the heads. I know it's a patience game with this.... do you have any recommended measuring tools I use to make sure everything is being ported properly and flow increased at a good balance or is that for the machine shop to test etc?
