CNC head?

[Sumsloppymeet]

Got this with my gt80 kit and was curious if it's any good anyone have experience with one similar I've noticed differences in the combustion chambers for starters which one is better possibly? Silver is the Gt5 head and gold is from MZMIAMI/ZEDA STAGE 2 GOLD KIT

The biggest difference is the color, minor differences are probably on the scale of tenths of a millimeter. You shouldn't see a difference between the two (well in this case feel the difference, obviously you can see the difference in color - you've already noticed it.)

They both look great.
It looks like the silver one has a narrower, deeper shape combustion chamber; the gold one has a wider, shallower shape combustion chamber.
I have read that the former is better for low RPM use and the latter is better for high RPM use.
Either way pay close attention setting it up, getting the right head gasket (or modifying the cylinder) so the squish gap is minimised to not have a lot of the fuel/air charge hidden in the squish band, but don't exceed the safe limits of clearance and/or cranking pressure.

Mine is like the silver one, and I love it. Although, I never even bothered to try the stock head!

Lol so far I haven't used the stock heads either lol

The silver one looks slightly bigger? Maybe it's just the picture and no side view pic of the gold one but the head looks taller with a bigger heat sink maybe? Both seem to have nice big fins to help keep the engine as cool as possible and both are very good upgrades.

The silver head has 16 cooling fins compared to 12 on the gold head. They both look better than the stock head. I would try both out, but pay attention to FURRY about clearances.
