Head skim requirement?

[MA70-3.0GT]

Even better, I have an electric shower that actually gives HOT water (unlike most) so it's great, all I have to do is move the parts over to the sink & rinse them off! Oh and being single kinda helps things along a bit too, no woman's tying me down unless I find her doing a crank job on her Skyline or summat!!!

I'm guessing the head bolts were never re-torqued then seeing as it wasn't run much. Definitely on the list for running-in then. Unless composite HG's are available in different thicknesses I'd imagine it's stock (vernier gives it as between 1.5 & 1.08 but it's been mullered about a bit since it came off anyways). I don't think I'll be doing much tuning-wise yet so I'll stick with 1.37 for now, if i do decide to "fettle" it a bit later on I'll likely tear the whole thing down again, skim & lap both head & block and fit a MHG to be safe.

For now all I'm after is a sweet running stocker with no BHG worries so I can get on & sort any chassis/brake or other issues that pop up when I get on the road...

That's the thing... Toyota only ever made the one head gasket for the 7M. I assume they expected you to just use it and not worry about the small increase in compression ratio until you had milled down to a certain level.

Hmm, seems I missed this post too! Been too busy hassling the bank for more money to get online much lately...

Anyhow, the head's come back as nice & true and should come up a treat. Think it's going to be well after Christmas though before I rebuild everything, mainly 'cause of cashflow but also my folks are moving house in a few days & I should really lend a hand with the inevitable mayhem. What a time to move, right before Christmas... It's 'cause our lovely, kind, giving government are putting up the duty on house sales (amongst other things) after then & well, we ain't the kind to avoidably line the pockets of a stinking politician...

So anyways, If I don't get back online before then, Merry Christmas to all & hope 'Supra-Claus' brings all the Toyota goodies everyone's wishing for!!!
