Angle Milling

It sure did work. My older friend used to run a 67 Camaro with a 283 in it. Dual quad tunnel ram and a set of angle milled heads. He is a crack machinist and did all the right stuff to make everything fit just perfect. Anyhow, this thing was making 600HP, N/A some 40 years ago. They were untouchable in his ring of racing for over 20 years with that car. He always claimed it was the milling and port work, and the 8500+rpm top end LOL
