OK, here we go... After extensive searching, I've found two camps regarding head bolts: 1) Clean em up and use the old ones, and 2) Buy new every time. The only reason for (2) would be if they are torque-to-yield bolts or damaged/corroded. The guys who post up that you are nuts if you reuse head bolts all claim that SBC's common to our trucks have TTY bolts, but this seems to be without substantiation. I have personally gone both routes in the past with SBC engines. I've torqued them all incrementally up to 65 ft*lbs. Never had a problem either way. I just picked up a set of FelPro ES72856 bolts, whose app. list includes up to 1997 SBC engines. The Fel-Pro bolt set (part number ES72856) appears in this catalog http://www.aaeq.net/catalog.pdf to be non-TTY. ----but---- In this catalog http://www.gimmecarparts.com.au/search.cfm?StartRow=36&searchtext=&SearchCategory=TP1133 the same set is listed as TTY. So some folks aren't sure what they're selling. Most other catalogs don't say one way or the other. The instructions in the FelPro box say to follow OEM torquing instructions (big help). The GM shop manual says to torque to 65 ft*lb. Edelbrock says to do the same thing http://www.edelbrock.com/automotive_new/misc/tech_center/install/6000/60909.pdf. These would indicate that there is no such thing as a TTY head bolt properly used in our engines. We are certainly not putting a chromoly bolt of this size into a yield state using just 65 ft*lb - also, all TTY bolts are installed via specified turning angles, not torque specs. So, all this being what it is, it would seem that re-use of old bolts in good shape is fine. Just clean them well, lubricate them, and torque in the correct sequence up to 65 ft*lbs (starting at 40, then 55, then 65 ft*lb). Any thoughts?
