'Pete, my 100 is all back together.. but you could just remove your header on your engines and see what I am talking about,, my headers are not mounted, so I will try to get a good photo for you, but I can't say how well it will come out being that the 90% Edge is inside the port, I wont be able to get the photos until tomorrow around 4pm eastern time..

I never painted, but I have rebuilt a couple Chevy small blocks (L79 327 Vett engine I put in my 71 Nova back in 79 and a 400 HP 350 I put in my V-drive boat back in 97) and a Chevy 4.3 V6 to re sell, and a Buick odd firing 225 V6, the 225 I built back in 81 or 82 for my 1947 CJ2A , that 225 was such a sweetheart, she had a CompCam Cam for low end torque, stock 2 barrel carb w/headers, she would never miss a beat when turning only 300 RPM as she crawl up over a rock or up the side of a river bank while pushing a constant 40 pounds of oil pressure.. the wife's uncle didn't like it that I swapped out the old and sick 4 cylinder Flat Head for the 225 until he got to see just how the 225 really did do everything better than the Flat Head, never the less the Flat Head was a cool engine. tiers were not that big, 11.00X32" Armstrong TrueTracks.
I sure miss being way up on the mountain cowling around in that Willys in the middle of the blackest of nights in 20 degree weather, some real fun there it was !!
