I used a couple turns of ss safety wire on each end with a twist and it's as good as the day I put it on. I'm not much of a fan of the header wrap but my first attempts at running the lines to clear the downpipes made me think it was necessary. By running the rubber pressure line forward and up to the filter mount I've kept the heat off.
Using the AN fittings and the rubber line is a bit more pricey than copper or ss but it totally eliminates any stress on the block fittings. There aren't many threads in the block and if you're developing leaks you could be setting yourself up for some headaches down the road. Have also noted that my oil temperature stays right at thermostat temp (180) and Speedway sells a slick cast aluminum cover for $20.00 that covers the filter can.
