Has there been any update on this?? Have you had time to work on it ssei1995?
I have been a bit busy at my normal daily job and also building a 331CID Ford small block for a friends Factory Five Cobra replica car.
Before I get blasted for doing work on a Ford...it'* just extra income.
I will be on the flow bench doing some more work next weekend on the ports. I have seen vast improvement on the velocity by straightening the exhaust runner. If you take a look at the exhaust runner, one of the walls is not straight. Also the floor is too high on the exhaust side and the short radius needs to be blended considerably. The addition of the larger valve helped open up the intersection to the short radius. The mods include modifications to the combustion chamber to unshroud the larger valves. I will keep you tuned as I proceed with the mods. I will be posting some pics soon.
I'm interested in the definition of "floor" and "short side radius", what they are supposed to do and why. I looked at the stage 3 intense heads pictures. they'd have a tough time getting $2k from me because of the small amount of material removed. It'* not making a lot of sence in Randyland.
Randy, read some of the articles I posted the links in an earlier message. Like I said before, when you are talking about cylinder head ports, bigger is not better because you can kill the port velocity. Port velocity makes power, not big flow numbers. That is the reason why the Intense cylinder heads have smaller ports.
Years ago I built an engine with cylinder heads that flowed 22% less than an identical competitors engine; my engine made about 42 more horsepower than the other engine on the same dyno. The other engine woould fall on its face at 8,200 while my engine had a flat torque across the RPM range and made power all the way up to 8,600 RPM.
Our cylinder heads can make the power, however, the intake leaves a lot to be desired.
I am also playing with the intake by adding clay to the floor to equalize the flow to all the runners. Add the end, I feel I will end welding dams to distribute the flow in a more efficient way. This will prevent some runners to run lean under boost.
