Has anyone else done this? I went down rabbit hole trying to find info on this all over the internet, talked to some shops/engine builders/tuners etc. and everyone says it doesn't fit and I would need to switch heads to the cobra heads. Well I figured it out and honestly it was quite simple versus what everyone else said...
First off I have a built motor in one of my cars that has ported navi heads. When i first got the heads from my tuner, my mach1/cobra lower intake did not fit. Luckily my tuner had a ported short runner(which is up for sale now) which I had bought to run with these heads. I ran this setup for years with a Vortech. I had a freshly rebuilt Whipple sitting on the shelf for awhile now and made the commitment to put it on.
There are basically 2 pieces of casting that stick out off the outer number 4 and and 5 intake ports in the valley.
I literally took a cutting wheel and cut them clean off so that they no longer interfered. The terminator lower intake manifold dropped right in so now its ready for the Whipple. Hope this helps anyone that has these heads or thinking about using these heads and has a terminator setup.
