Default head bolt diagram

Does anyone know where I can go to print a diagram to see where what head bolts go where? Any help is appreciated.
Thanks.... <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

Look at www.blackcamaro.com and look at the "ARP Head Studs" page. Numbers 9 and 10 are the short fat bolts, 1-8 are the long fat ones, and 11-15 are the little bolts. They get tightened in the order shown.

JMX has got you covered. It makes the head swapping quick and easy with the details on the web. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

I don't know if that is your website, but there is some wrong information givent there regarding cams.

This determines the time between when the intake valve closes and the exhaust opens. Too small and you get overlap, where they are both open at the same time and you can get fresh air and exhaust mixing (that's bad)."</font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">LSA is the angle between the intake and exhaust lobe peaks. As such, it describes the angle between when the exhaust and intake valves are at max open point, not beginning to open.

Also, overlap is determined by both lobe durations and the LSA, and is a good thing up to a point. It is what allows the exiting exhaust help pull in fresh fuel-air at higher RPM's. At low RPM's, it causes some exhaust gas reversion, contaminating the fuel-air charge, and that's what causes the lumpy idle.

If it isn't your website, don't sweat it. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

I assumed it would be read as peaks, but also figure that it should be accurate for the generalization too?

The overlap statement is another generalization, was trying to keep it simple....

Thanks for the heads up

</font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">Very true; it doesn't matter where you measure from, as long as it is the same point on both lobes. I think it is traditional to measure between lobe peaks because it is much easier to do so. This reminds me of the old way lobe duration was measured, now called the "advertised" duration. It is much easier to measure from .050 because that's a better refference point than trying to figure out exactly where a lob slope starts.
