Sorry guys almost overlooked doing this but here is the port energy density of my students design of big block Chevy port as applied to the EQ iron heads.

This graph of course won't mean much to many of you as you will have little reference points here but if those lines within the lift range we are using go much over 20 with a big block Chevy head we can say that the port is in the top 5% of what you can expect to get out there. Most big block Chevy heads don't make it to the 20 foot-pounds per square inch per foot length port mark even at lifts high as 800 thousandths. All in all these iron EQ heads really do appear to be the best iron heads out there along with their ability to compete with many recognize successful aluminum high-performance heads.

My assessment of the cylinder heads then is that they are top-of-the-line for iron heads and if we're just talking about heads in general they are amongst the best out there. For those of you who are interested I have produced a YouTube video so watch out for that it will take a close look at some of the things my talented student applied to them.

David, do you still have that mold laying around? I'm anxious to see your new videos, too.

SERIOUSLY thinking about purchasing a.set of these heads for somewhat of a street sleeper project.

Anyone know if there Is there anyone out there with a CNC program for these heads or who is working these heads by hand?

Two places to go to thjat I know can do a good job right down to getting the best port energy as well as good flow so big torque & HP #'s are about as close to sure fire as you can get.

#2 Charlie at ------- sorry brain surgery damage strikes again. I canot remember Charlies contact details - can someone help out here?
