Does anyone have a picture of ported exhaust port/guide area on a 6293 head? In addition does anyone have a flow sheet of a pocket ported/gasket matched stage one iron head? Thanks for the help.

Sir,
Thanks for the Pics. By chance do you know how much can be cut down on the height of the exhaust guide in the bowl area? I seen that Champion cuts them all the way out and I am not sure that I want to take that risk of the valve moving around with heat. I might be over thinking it.

I like to leave some length while streamlining the shape. To me totally eliminating it is the fast and easy way.

Sir,
Thanks for your response. I will leave it in there and reshape/profile the guide area.

Kind of a joint venture between myself and a friend who has stepped away from doing work for the general public.

I did the port work and he followed up with an incredible valve job that not too many others could have pulled off. NO room for mistakes.
