After installing my new Gil manifolds , I want to do a jet/plug check. What cyls run the hottest? Its too hot in the engine bay to check em all if i dont have to. Do you normally have to jet up when installing manifolds?\
thanks sj

I always check #5, 7, & 2. I have lost more pistons in 5 & 7, that is why I check those. #2 is to get one on other side.

No telling what you will need to do when you change manifolds. I they breath better you usually have to jet richer

# 1,3 & 6 are what I was told to always check
