I'm putting together a k24a1 frank with a k20z3 head. Block and head are completely stock, and I'm using an OEM TSX headgasket. I'm going to run a 50 degree VTC gear, and was wondering if anyone had run this combo before and experienced any problems with the full 50 degree VTC advance. I know the proper way to get the answer is to clay the motor, but I'd rather not have to go through the hassle, especially if someone's put together this combination before. Thanks in advance.
