Fleece Cupless heads reviews/updates/opinions etc?

[DieselDemon18]

Hey fellas, thinking about l running cupless heads on my motor build, currently building a fully built bottom end, going in my tow pig/fun toy that will be roughly 5-600 hp with the potential down the line to be modified to 7-800 hp but i highly doubt that, building more for reliability. Anyhow anybody have some reviews on the cupless heads? Good, bad, or ugly? I just want to address the weakpoint while its all apart, but for 2k i want to make sure im getting something good first want to make sure theu can handle heat and abuse, i tow heavy with a lead foot so i want to make sure the heads can handle the thrashing

Have you considered threaded cups? Much cheaper and basically the same in the end

I've had zero issues with them.

Had a set on my Suburban for about 9 months now. Heads seem quality, and the machine work / prep on them was all done well. They appear to be very close to stock design, so don't expect any power increase. I got them on sale and they worked out about the same cost as redoing my current heads and adding the screw in cups.

I'd likely buy them again if I end up in a similar situation.
