yes...but specifically "FULL ROLLER ROCKERS" compared to normal ones or the roller fulcrum ones from some GEN2 aluminum head motors. They fit using the F-body gasket under the Fiero gasket but without the spacer, oil leaks will happen.

I was simply pointing out, that it is proven that roller rockers aren't really worth anything from a performance standpoint. roller fulcrum, like LSx and 3x00 rockers offer ease of assembly for OEM compared to having to adjust a ball fulcrum, you mentioned the low lift of a stock 3x00 cam with 1.5 rockers, and I showed that you can obtain a 1.6:1 rocker dirt cheap, without having to use spacers, bolt in and go, with 4 spares for well under $100.




Perhaps not perceivably when they are the same ratio; however, there's usually less friction which means less heat and somewhat more efficient, and they're typically less noisy. So, all around a better option to normal stamped rocker arms.

Took several 3D-printed prototypes before I sent the final design for CNC cutting.
Had to learn how to convert an .STL file to a .STEP file as well using CAD software. Took a bit of work. I'd like to do more stuff and that's why I started a Patreon page incase the community wants to sponsor me to do even more.

Glad you like them.

Another advantage of the Aluminum rockers is heat dissipation.
Being aluminum they don't hold the heat like steel does.
That is why the majority of heat sinks are made out of aluminum.
So, if you are using one of Lou's aluminum spacers you are also adding and extra heat sink to take away heat from the heads up to the valve covers to be dissipated more quickly!

Nice - simple solution.

I always ran roller tip rockers rather than full roller bearing versions (Comp Cams sells reasonable ones) to avoid this issue as I don't feel that having full rollers is worth the fuss, but it is nice to have an alternative.

Most will want to keep a stock looking intake in their Fieros, but I'll warn anyone that thinks of using a later F body intake which flows a bit better, that with the Fiero valve covers there is a bit of interference with the top of the covers and the bottom of the manifold. It is easily dealt with by some minor grinding on the underside of the Firebird/Camaro intake, and the Fiero valve covers sure look nicer than the stamped steel versions. The fit without grinding is so close to looking right that you might assemble and think everything is buttoned up tight until you hear the intake whistle as air sucks by the very thin aperture left when the manifold bottoms on the covers (don't ask me how I discovered this).

The last post was 2019 and you got them today?

Yes, I had saved the post from 2019. That's when I was building a motor. We are just now getting to the point where the old motor is out and I am getting things ready for the transplant.

I reached out to see if they were still available, and they were...
