Anyone running these pistons? Im wondering how much lift at TDC they will take, and if the valve pockets are big enough for 1.900 / 1.625 valves.

 

Problem is that the pistons are cast...which means they are not all the same in one way or another. If your using 1.900 or larger valves you need to clay the pockets and eyebrow to see what you have, thisis the only way to do it and feel safe that interference won't be an issue.

 

We use forged pistons for the consistancy and strength. We have them made with modified valve pockets so the valves will clear our cams with shaved heads. We stock 95", 98", and 107" and have already fitsets on the shelf for quick turn around.
