The lumps do not follow the roof of the port that well, I did not take enough time to do that.You can get the shapes close & fill in the gaps w/JB weld. :-)
These lumps were made from billet aluminum & it takes a lot of time to shape them perfectly.
Yes the back of the lump was suppose to be winged shaped to help direct the air/fuel mixture around the valve bowl area.
tlowe I.I.#1716 , I believe if you completely divide the ports ,the port window gets too small, forceing you to have to open up the entrance to the intake port, causeing the air velocity to slow down too much (not good for normally aspirated) unless you are super or turbocharged,where the air is being forced through the port.
Tom & Douglas I will send you some pics also!!!!!
