i found a deal they are 2000 deg ceramic coated and have the zzp pro kit with 1000 miles on them for 350....then ill just get SDD clamps and gaskets...you think ill be happy they are 1 3/4 primaries but ive heard gtps shouldnt have a rpoblem running these over 1 5/8 thats its more the N/A motors that need to be careful right?
