You listed that you had 69 ported heads ... from the tests i've seen a good port job on a set of 69 351 heads with the 1.94 intake 1.6 exhaust valves flow better all around than GT40 p's in stock form. If thats the case then how much are you gonna gain per dollar spent ?
I'm sure there are people here that will disagree with that but thats my 2 cents worth
