Some TrickFlow curiosity work
I wanted to address this a little better today. On these heads I plan on either changing seats and or keeping this head or seat of heads for testing purposes. I never cut seat on my seat machine if I am going with a bigger valve because the cutter will and does hit the chamber. Especially when using my favorite 4 angle cutter. At least on the Speedmaster heads the have a slight cut that is made cutting their seat. I wasn’t up to getting in my porting coveralls so I was just experimenting. Here a picture of a Speedmaster head before I do my chamber work for the 2.055 valve these are getting. Love to show an after shot but it usually bites me in the butt and it opens a can of worms an comments I’d rather not be faced with. But yes you do get chatter on most seat machines so the seat angle get dressed and vacuum tested.
