ProComp/Speedmaster aluminum heads

I would be willing to bet that even the Edelbrock stuff isn’t made in America. That being said I always changed out the retainers, keepers, and springs as part of my upgraded. We did have a chunk of a stock intake valve break off in one of my sons engines which required me to pull both heads to fix it because the piece traveled from number 3 cylinder to number 6 cylinder

Likely not I suppose, I think the difference is in QC. Inspection and rejection of the inevitable bad parts when buying from China. I would think/hope Edelbrock does a better job than SM.

I've been looking at the trickflows, and $2400 loaded and ready to go is a good deal vs the normal price of $1800 for the loaded SM heads.

That's what I was looking for, didn't go enough pages down, page isn't great on phones, and no real way to filter. Thanks.
