I am changing intake pipes and exhaust manifolds on my IO-360 parallel valve RV-8. The long story about why is posted here: URL="http://www.vansairforce.com/community/showthread.php?t=31370"]http://www.vansairforce.com/community/showthread.php?t=31370[/URL]
One intake bolt has some thread damage and the nuts and lock washers on the exhaust studs are rusted up a bit.
Four questions:
1) What size nuts go on the exhaust studs? - found this: 5/16" - 18
2) Are the lock washers special steel because of the high temperature?
3) What AN or MS or other spec bolt is used on the intake pipe?
4) what is a good source for 1, 2 and 3 above.
Thanks,
John
