Got a 426ci with 4-.024 injectors,s300 turbo, stock cam advanced 9 degrees and Murphy’s rockers Limited to 3000 rpm. Did the standard pocket port cleanup under the valve. is there much to gain taking 1/8” out along the right side of runner on the exhaust port. Seem to me it would lessen the curve on that side and not be as restrictive or would it lose to much velocity
