Yep those can be a pain! <br /> I just removed a head on my 120 OMC used penetrating fluid, let it sit then used an 1/2 in impact and correct impact socket to remove some, a few were too tough for even that, I then used a big breaker bar and my foot for leverage.<br /> if that does not work try heating the bloch around where the bolts are threaded in this will expand the metal surrounding them, then hopefully you can pop em loose.

A 470 is totaly different from a 120.GM engine.<br />Do nothing, untill an old 470 Merc. guy tells<br />you how. The 470 is a very unuasual engine.<br /><br />Wait 24 hours - some one knows.

Hey Kid,<br />I don't Normally work on 470s, but seeing your a Maineiac(I was born,+ raised in Old Town), I dug out my book......<br />There's Nothing Special about removing your head... Loosen All the bolts, Starting in the center,+ working your way to the ends.....<br />After removing the bolts, tap the head with a block of wood to break the gasket free,<br />Then remove the head...........<br />As to What Wrench, I'd go with a 1/2" Breaker-bar, with the Proper sized 6-point Socket.......<br />If you Need more Power, Add a 4' pipe to the handle of the Bar..... That Should give you Plenty of Torque......<br />If you can, find a Helper to keep the Socket True to the head of the bolt....<br />When they break free, It'll be with a Bang.....<br />Yes, they're standard right handed threads..... Turn them Counter-Clockwise......<br /><br />BTW, If the 4' pipe Doesn't work,<br />Get a longer Pipe................................ <br /><br />Good Luck.......
