Buy a VTX. But if you must...

- Crank engine until both rocker arms are free (cam followers on base-circle, valve closed.) COMPRESSION STROKE RIGHT AFTER EXHAUST WITH PISTON AT T.D.C.
- Remove any other parts that are in your way. Trust me, it's easier than working around them.
- Remove cylider head bolts. Place in a clean, dry place.
- GENTLY tap and pry head away from cylinder and gasket.
- Pull out the pushrods and tubes and place in a clean, dry place.
- GENTLY tap and pry cylinder away from crankcase and gasket. WITH YOUR HAND

- Using a razor-blade scraper, remove the old gasket and any sealant residue from both cylider and head.
- Wash away all grime and debris with solvent or Formula 409.
- Tape a full sheet of 400 grit sandpaper to a firm, flat surface.
- Move the cylinder sealing face over the sandpaper in a figure-8 motion until any evidence of etching from the leak is gone. Repeat with the head. Wipe off dust and grit.

- Install head. Torque bolts equally in a cross pattern. !!!SEE BELOW!!! 350 ft-lbs should be enough. ARE YOU KIDDING? NOOOOO.
TIGHTEN BOLTS IN A CROSS PATTERN, OUTSIDE LEFT, INNER LEFT, OUTSIDE RIGHT, INNER RIGHT TO 7-9 FT LBS, THEN TIGHTEN ALL IN SAME PATTERN TO 12-15 FT LBS, THEN TIGHTEN ALL TO 22-25 FT LBS, THEN FINISH TIGHTENING TO 38-42 FT LBS. IF YOU TIGHTEN THEM TO 350 FT LBS, YOU WIIL TWIST THE STUDS OUT OF YOUR ENGINE CASES AND RUIN YOUR MOTOR. THE PERSON WHO TYPED THIS ORIGINALLY SHOULD HAVE DONE THEIR HOMEWORK.
- Install remaining chrome gobbledy-gook. (OBVIOUSLY HATES HARLEYS)

- Lather, rinse, repeat.

Does your car always over heat when your head gasket is blown?
the answer is that if you blow the head gasket your car will overheat if you are driving any distance at all. You should smell coolant and see signs of leakage. It could be that head gasket is fine but you have had the bolts around the cylinder head work lose or be improperly torqued down.
If you do nothing but drive short distances and the gasket is leaking at back end of clylinder many times it will just lose coolant of course this is serious too .
If you see coolant leaking it is many times serious not just a hose or fitting .

How do I know if I need to replace the head gasket on my car?
If you are loosing coolant with no apparent leak, sweet smell at the exhaust, coolant mixed with the oil, air bubbles coming out of the radiator, (engine running, cap off), foamy substance on the underside of the oil cap. All or some of these is a sign of a blown head gasket. To verify this perform a compression test on all cylinders. Low compression on one or more cylinders is suspect.
