Hope to start the rebuild by the end of the month. Longblock will be completely stock as well. I will also keep everyone informed on how they hold up.
Heads are holding up nicely. several round trips to NYC at stupid MPH. MPG sucks when yer going stupid MPH but the whole engine is holding up nicely. round trip is about 450 miles. 8-9 hours with gas stops going 70-75 as high as 80, when ever traffic allows, which is most of the way. Some what hilly but not anything like the hills you guys have in the PNW.

Paint did not burn off. Rust has come through in only 6 -7 weeks. May hold up nicely in a very dry climate.vdubyah73 wrote:rustoleum 2000* exhaust paint, use the primer as well. I sand blasted a 1 month old empi single quiet pack "extractor" exhaust after the og paint burned off and it started rusting. I removed the exhaust and sand blasted it clean of rust and remaining paint. 3 coats each of primer and paint. each coat consisted of 2 light coats and 1 full coat. meaning start at 1 end and when you get to the other go back and start over right away. wait 10 minutes before repeating. remounted and ran at idle for 10 minutes then cool till your hand can stay on it. repeat 2 or 3 times, then take a 30 minute ride, try for some highway time to get some real heat into it I went about 5 miles at 65-70 then toodled back home on surface streets. No paint has burned off, no rust has shown yet. I painted it about a month ago, bus is a daily driver, combo of surface street and highway driving.
the rustoleum seems to perform as advertised, I'm satisfied so far. will report back if and when rust or burning paint happens.
PS: the muffler is junk right out of the box. the flange should be reusable to replace with a quality one, when it falls apart from the inside out.
