[Don Quixote]

I appreciate you! It was a lot of work for 1 guy on leave with a tight window. The whole truck is much like Cajun cooking, a little bit here and a little bit dere.

Thank you for the heads-up. I thought about that but I have also heard it is just about impossible to seal the outside exhaust ports using the cast headers as they are a 2 piece design. This is another reason I use Grade 5 bolts on the manifold and Grade 8 everywhere else, aaaaaaand I chewed up the studs pretty bad pulling them out.

I agree with you on the .010 at a time. I don't think I would go over .055 as I've seen bad things happen to all the electrodes between the plug and the rotor with a bigger gap.
