I have been getting a lot of inquiries about these heads and what intake and camshaft to use with them and wanted to start this thread to get some of those questions answered.
I am sure some of you IMCA guys are into it.
I flow my stuff different than most as I use 25" and I also use intake and carb bolted to head to determine changes.
I figure that is what the engine sees so that is what I look for.
I don't want it to turn to a thread on what the heads flow and how can you cheat them up because they will make more then enough power 100% legal if you do the hard work to get there. And I know there are a couple folks out there doing it because I am working with them to get there.
If you want flow numbers on the head you can go to the EQ website although there numbers seem high to me, but I don't know if they were using an intake radius and what bench and flow depression they were using. All of these things can vary results up to 10-15% or more. On 200cfm that is 20-30 cfm. That is the difference of close to 50hp at 100% VE.
