FE Technical Forum / Re: Trick Flow heads....
« on: May 12, 2019, 03:50:33 PM »I thought it would be informative to post some mechanical drawings of what good rocker geometry looks like. The obvious difference is that with correct rocker geometry the travel across the top of the valve is reduced, and that brings benefits in terms of wear on the valve guide and reduction in friction in the valvetrain, especially if you are not running a roller tip rocker arm. From the pictures I've seen the Trick Flow heads look like they come out of the box with rocker arm geometry similar to what is shown in the first picture below. Will they run like this? Sure. Will they make power? Of course. Is it the ideal setup? Not by a long shot. This is why the rocker pads are being cut down by some of the folks here. Longer valves would also solve the problem. Since Trick Flow is offering the heads and the valves, it seems odd that they set it up this way. Seems like a design or manufacturing mistake to me. I hope they can get it corrected.
Only problem is that your drawing isn't accurate. Do you have a set of TF heads on your bench? Do you have the Comp rocker arms on them? If not you might not have the drawing correct. We didn't see any of the problems that people are talking about. I'm guessing that nobody on here has Comp rockers on the TF heads? If not then why does everyone all worked up? If you haven't built it and tested it then what makes you an expert?
