I watched a Skinner twelve port on a 292 Chevy make mincemeat out of those Drag cars in its class. Many couldn't believe that it ran that good. I had heard the designer/builder had passed away. My only comment is if you like an inline and want to go fast if this head fits what you have and it can be bought for anything less than six grand grab it. Look at what the high perfomance V-8 heads with a special set of gaskets goes for today. None of it is cheap and the inlines making a great sgowing almost takes me back to my childhood. Our 216's 235's and an old 248 Jimmy all ran good for me! Look at them when you open the hood and they get a look at what just showed them the tail lights at the finish line. Stunned usually.
