It's not my style to bash someones idea's and or products especially out in public. So I really have no comment on how or what Lynn's heads are capable of .
I can tell you that my 5 heads do flow very well as cast and respond well to porting. They sound really good on the flow bench and do not back up with a fairly conservative valve size. As for wet flow !! I really don't know what they will do yet. So I cannot spout off or beat on my chest until I have solid evidence of what I did with my port design will work. I have done some computer generated models of the flow path with my port design and that is how I came up with the design I did, but until the rubber hits the road. I am purely speculating. I have built several factory Ram Air 5 engines in my career, and I can tell you that they all liked rpm's even on bigger cube engines. So I knew that I had to increase port speed without sacrificing cfm to improve the factory heads. I have never wet flowed a set of ram air 5 heads (mine or factory), but if the wet flow is bad. You cannot tell by reading the spark plugs. All of the RA 5 engines I have built. When you pull the spark plugs they all look really good even after idling for extended periods. In my experience over my 30 + years of doing this. I have found that if you have fuel dropping out of the air from to much carburetor,poorly ported or designed heads, the wrong intake or anything that allows fuel separation. The spark plugs look like black wet pieces of @#$%, and all of the tuning in the world cannot fix it. So do I think there will be some wet flow issues to deal with? Maybe, but know one will know that until air and fuel pass through the engine. I do know though that you don't need a pushrod tube running through a port to have wet flow issues. I know that for a fact!!!!
I really did not start this thread to start a negative path, but a positive one to inspire and promote advancement with a traditional Pontiac engine. I some times wish I was like the rest of the herd out there, and liked Chevy's or Ford's. Fortunately or unfortunately, I guess it depends on how one looks at it. I have Pontiac blue blood and I cannot help but try to try and improve them. So if you guy's don't mind. Let's get back to the subject matter here.
