Going to do LT's, need a tap and specs please!
 
Ok, when I put my manifold back on my car after the H/C swap one of the bolt holes got cross-threaded. I need to re-tap the hole in the head for the header bolt again, and clean out another one, what size tap do I need and what pitch ect? Where can I get one for a descent price?
thanks

Ok, i found this page http://www.discount-tools.com/rfn-100ms.cfm and they have it for $13.77 (sorry if it's not a sponsor, none seemed to have one) Now, I want to use a hand tape right? How do i know if this is going to fit between the head and the engine bay?
thanks

You should be able to find one locally, that will save some time. If the autoparts shops don't have one, try an industrial supply or machine tool supply (lathe & mill.) It's going to cramped in there; the standard T-handle used on taps might not work. You can use visegrips, but be careful; use plenty of cutting oil and reverse direction frequently to break the chips. Yes, use a right-hand tap.
