I have some Trickflow heads questions. Trickflow sells a head bolt and head stud kits. 440 source sells 2 different head bolt kits. I have TTI 1 7/8 inch E/B body headers. I normally would use a stud kit but thought I read somewhere a person that bought the stud kit had some interference issues and they had to grind the tops of the studs. Any advice or experience with this? Thanks everybody.
