Quick question: If I remove the bolt currently in the head at that position to measure it and/or to replace it once the new one arrives, do I need to be concerned about a head gasket leak at that point later on or can I just remove it, replace and re-torque it without affecting the seal on the gasket? What is the torque value for that bolt by the way?
BJ

HO exhaust manifolds.... arrrghhhhh...... after spending $140 having one repaired (pro welded) we found small cracks on the other one! I give up on old iron manifolds that have seen years of heat.... Buying some oversize RA Ent. new ones...... I cry uncle! Cool garage hangings they will be (the old ones)..... arghhhh.....

Also decided for my new done HO heads, to do the bottom end right.... was going to freshen up the low mile 4 bolt bottom end I have, as it is low miles, but decided to get some good rods to replace factory. Pro balance and do it right. Hopefully my forged pistons are fine for re-use, should be. Any rod recomendations?

You can check out what I used for my engine:
http://forums.maxperformanceinc.com/...695444&page=32 When we balanced them, it turned out they were all within weight spec and needed no additional massaging for weight matching. Very nice set of rods. |

on a stock, to mild build stock rods are fine, and the >> cheap forged rods <<<< ( SCAT,CAT) always need more balancing and resizing.... Buy some lightweight pistons and spend money on balancing IM (HO) ! |

I see the forged rods as insurance. And they were comparatively priced to having the old factory cast set completely redone and buying new rod bolts, too. Forty year old cast iron can have unseen stress flaws just waiting to find the most expensive part to take with it. (your matching # block). The rod set I got was perfeclty weight matched right out of the box. On my prior HO, i did reuse the forged pistons that the prior builder installed. It worked out fine, as they didnt need any further massaging for weight, since they were previously balanced.

so anyone need a nice, blasted clean drivers side 72 HO exhaust manifold (no cracks)? It is useless to me since I am buying oversize new pair. I will keep the bad passenger one as a cool garage ornament.... if anyone could use I would trade for ? or go cheapo....

Sunny O is indeed code 65 on the cowl tag, and "Z" on the invoice.
Nicely optioned '72 HO Formy! Tilt Formula wheel, gauges w/ tach, Y99, both consoles, KR Rallys, Safe-T-Track, and so on . . . Just like what I'd have ordered, minus the cordova roof, add the factory spoiler and change to the "tuxedo" guts. Looks like it's not TOO far gone to be salvageable . . .
