whats the issue with the valve clearence cause it says that with the afr heads that the pistons have to b notched for clearence and the specs that i got with my 347 said that the pistons were allready notched and ready for use of the gt40x heads..i called ford to ask them cause ive heard a lot of good things about afr 185s and the guy told me that ide have a 95% chance of the afr's fitting but i dont want to by them and not have the rite clearence on them if the pistons are already ready to go for the gt40x heads.. does n e one no if they use the same clearence and if the afrs wood work good
