"ProMax" cylinder head review

[EWC]

It would make more power if you had a manifold to match the heads .

Just cause somebody can make big power out of these on a short burst does not mean they are good choices for the long haul or for pulling heavy up a grade. Just say-in

From what I have seen of comments so far, they look like great candidates for a motor that I do not plan to keep for long or work hard. They do look good for playing around on proof-of-concept platforms while working toward a long term solution. From all the rough casting surfaces and reportedly lose slag all over the place, it raises the concern of adding opportunity for cavitation and debris to wear the impeller.

Then again, if the only point of this discussion is to highlight what looks like a disposable product, seems like a good one to me

So you are quoting a reply we made to make a post entirely transparent to the public that the run was done with meth? What's your point again, exactly? Should we have hid that and let people believe it was done on fuel only?

This post is about cylinder head flow and it doesn't matter what fuel you use to make power to move air through them for this discussion. Please quit repeatedly wasting my time with your games.

Easy cupcake , I was just curious on what the truck made on fuel alone. But once again you didn't provide an answer... big surprise there. If you post dyno sheets people are going to have questions off topic from the original post welcome to the internet.

Im not sure if you have the worst ProMaxx heads ever sold, or that I have the best ones they ever made, What I do know is the ones I have have no slag , smooth throughout , a slight shift in bowl blending everything else looks as good or better than an Edelbrock casting. Looking at your pics you had every right to say they are $hit. I guess its the luck of the draw, whoever purchased those should have not accepted them , and returned for a refund or replacement.

Do you have any pictures you could share?
