Hey all, I've done just about everything to solve the intake leak on my 64 C10. The problem is, the damn leak keeps coming back. 292 I6 with Offenhauser 4bbl intake, and Langdon Cast headers. I'm running those fancy Remflex gaskets AND I got some of the McMaster Carr spherical washers to account for the difference in flange thickness between the headers and intake. I installed the gaskets dry as per the Remflex instructions. Due to the position of the bolts, it is nearly impossible to torque them to 20 ft lbs, with any torque wrench I own. The truck seems to develop an intake leak after a couple hundred miles. Upon the typical loose intake symptoms showing up I constantly find that the intake bolts are loose. I'm contstantly re-tightening these things. Anyone ever use lock washers with these McMaster Carr washers? The design seems like it may hinder the ability of the lock washer. How about Loc-Tite? What are you guys doing to get some distance without carrying a 9/16" endwrench in your pocket, and burning your forearms on the tube headers?
