I'd go 70 ft/lbs (or even all 72). As for the backing off of torque, that's up to you. Would hurt to turn 'em all out half a turn (make sure you follow the proper loosening sequence) and retorque to 60/65 then make a final pass to 70.

It's kinda hidden in the TSRM - you can check my build thread for what I measured as a comparison but I'll find the TSRM page details and post those up shortly. You check the distance between the shim and the cam lobe when it's pointing away from the shim - just in case you didn't already know...

Nice work! I'm so loving that nike mod too! Your intake manifold looks rediculously clean, actually it all does! What did you do to obtain that sort of finish?

One of the duties of the catalytic converter is to change the harmful exhaust fumes into something a bit nicer. One of the components of a properly working cat and exhaust fumes is H2O! Still could be fuel though. And if you have no cat, my whole post was meaningless!

Hah, this one had me too! Funny how the mind processes this sort of statement. Here's how this works: the flat portion where the cap mates to the head gets a bit taken off, this ends up closing the gap between the cap and the head. You end up with a slightly distorted circle as a result but...

LOL!!! Fig, am I understanding correctly that you never disassembled the valve assembly from the head? To answer your question about valve job vs valve seal replacement, they're not mutually exclusive but you can do one and not the other. A full valve job involves removing the valves...

Best test is the "fingernail test" if you can feel it with your fingernail, you'll need it honed at least but likely bored as well. There's a good chance that if you can see it, it'll need machining. Especially when you're talking about the sort of damage your piston has just sustained...

Denatured alcohol should be pretty much the same as our "metho" over here Hells. Just grab some from a hardware store and you should be set!

I should have stayed and watched them do it. I'll have to see if there's anything online that shows how this is done (very interested in the machines that do the block as well).

Is that a lot? I've measured in other spots on the head and have some further questions. If the top surface is irregular, the measurements are going to be different, depending on where you measure from. I haven't recorded all the results yet so we'll see how much variance there is. It...

DOH I'm such an idiot!!! I was thinking the head surface had higher points than the "top machined" surface. Ian, no wonder you mentioned splinters! Sometimes I scare myself... OK, the head is almost exactly 116mm (4.562" = 115.8748mm). I'd say he didn't remove much!

Two controlled surfaces from a cast head, makes perfect sense! Thanks for clarifying.

Top gasket surface? The valve cover gasket surface? *scratches head*

And just that much spray does it eh? Fascinating! I actually thought that hole was to spray the cylinder wall!

Been having issues on this PC (my wife's) for ages but never on mine. No spyware, no other problems with any other programs to the best of my knowledge. Of course, I've never spent near enough time diagnosing the issue (shame on me...). My PC's unavailable as I'm fixing one in it's place at...

:LKUEO{YHG PL:KH JSGD":LKJW COmputer!!!! I've tried posting 3 times now and IE keeps crashing... Firefox here I come.

I'm sure this has been answered before but do you know what reference point to use on the top of the head?

I wish man! I'm replacing motor mounts on an SR20 Pulsar tonight (mother-in-law's car). Plus giving it a tune-up and a few other bits-n-pieces... But the day is still young - we'll see!

Lifting the head would suck! I'll investigate that a bit further. I don't know how much was shaved because I forgot to ask... The block's being decked as well so a bit higher compression is going to be the result, one way or another.

PICS Clean but still needs some internal scrubbing and a few odd 'n ends.
