Head bolt size? help?
 

Hey whats up stangers? Im going to be ordering up parts for my motor build up, Im going with F-303 cam, Trick flow intake and heads, only thing is the trick flow heads come in two head bolt sizes in the summit catalog im looking at it says for either 1/2" or 7/16" which one do I need. My motor is a 88 LX 302 with 60,000 original miles. Also what do you think of that combo of parts? thanks
