Has anyone heard of Engine Pro Cylinder Heads? I can't find and information on these.
There Aluminum heads with:
64cc chambers
210cc intake runners
I found a set of these with stainless steel Comp Cams full roller rockers 1.5 intake and 1.6 exhaust.
I'm contemplating upgrading from my Vortec heads which I think one of them might be cracked because I keep getting dirty water in the radiator.

I did a quick search and didn't come up with anything. They must have another part of a name or something.
Maybe like Procomp or something. You turn alot of RPM's. I would make sure the parts can handle it first.

So I found out they are overseas castings that are sold by Engine Pro.
RPM Racing out of Sandy sells these. They said that they install and sell these heads and have not had any problems. RPM Racing has been around for a while so I would not think they would sell anything they knew was junk.

So I ditched these heads and picked up a set of bare GM fast burn aluminum heads. Now I need to get a little machining done to fit 2.02/1.60 valves and get the valves and rest of the hardware.

Here you go. There cores from an enigne builder for the roundy-round racers. I need to do more research to see if I will benifit from polishing the ports or if it will hurt the factory vortex design of these heads. I read that you can mess up the vortex flow if you port these heads.    |

What do the combustion chambers look like? Yes you can mess up the vortex if your not carful. I would put a gasket up to the intake side and see if you need to do any work first. Remember the intake side should not be polished. Its designed to be a little rough to help mix the air/gas into the perfect explosive blend. Porting\gasket matching and polishing the exhaust is easy. Same with polishing the chamber if it is not shiny already. By taking out any ruff areas it will not allow carbon to build up and allows the spark to be more effective and the exhaust to exit smoother and faster. If you want help, please let me know :-) I have the porting/polishing tools and am in practice from working on the jeep heads. I also have a book that helped me and some YouTube videos..

Here's the combustion chamber. It'll took better after I get the heads cleaned up.  |
