I need more info on cam shaft timing after installing the cylinder head. Does the single dot on the intake line up with the two dots on the exhuast cam with both lobes facing out on intake and exhust on #1

You can find the timing mark on the end of a crank shaft by looking for an indented dot which marks top dead center.
A flywheel is balanced and does not need a mark. However if the wheel you refer to is a cam gear (one or two gears depending on how many cam shafts your engine has) look for 2 dots with a tooth grove between the two dots. A matching drive gear will have a single dot aligned with a tooth on the drive gear. When put together the single tooth marked on the drive gear must fall into the grove marked the the 2 dots on the cam gears.
If you are just trying to time an engine, the belt drive pulley mounted to the crank shaft will have a single indented line. The line can get filled with dirt so you can't see it. Wipe it clean and fill with grove with something to highlight the groove, as with a white or yellow crayon or a dob of bright paint. Associated with the belt drive pulley, there should be a metal plate with line marks spaced on it, with 0 degrees (top dead center TDC) marked on it, When the engine is running, using a strobe light connected to your number 1 spark plug you will see where the timing mark on the belt drive pulley is compared to the metal plate with the timing marks.
There's a dot on the cam and a mark on the head turn the cam over with a ratchet and socket it should pop into place be sure to line up both cams one on each head and the bottom on the crank there's a mark on the pulley for the belt you should buy the timing belt kit it comes with new idler pulleys and you should also change the water pump while your in there it runs off the timing belt the new timing belt I put on had dots on it to help line up the timing marks
Exhaust camshaft gear and Intake gears have dots on them, chain has colored links. Align colored links to dots or count 14 links from ex cam dot to intake dot. Make sure that the mark on the cambelt side is set first on ex side. Small hole on ex cam gear (cambelt) side to line up with mark on head.
TIMING MARKS ON CAMSHAFT SPROCKET A LITTLE SMALL SQUARE MARK ON TOP BOTH GEAR SPROCKETS ON CAMSHAFTS TIMING MARKS SHOULD BE IN THE 12 OCLOCK POSITION BOTH CAMSHAFT TIMING MARKS SHOULD BE LINED UP WITH TIMING MARKS REAR OF TIMING MARKS ON TOP OF CAMSHAFT SPROCKET HOUSING. IF STILL HAVING TROUBLE WITH FINDING THE TIMING MARKS.YOU NEED A HAYNES REPAIR MANUAL.
6 Cylinder petrol: Align crank(C) timing notch mark (1) to oil pump mark. Align cam pulley(L+R) marks(3) to cylinder head marks The cam belt has 3 marks, 2 lines and one mark that is actually a row of dots. Align the dots to the crank pulley groove mark(2) and align the other 2 lines to the cam pulley marks. Using a clothes peg to hold the belt to the cam pulleys works wonders to keep it in place while fitting. Please note the arrows on the belt and have them point in the direction of rotation - right to left side of engine W - water pump pulley I - Idler pulley T - Tensioner pulley.
If for some reason you need to realign the cams on each bank : Standing
in front of the car and starting from YOUR left , looking at the cams
you should see RE, RI, LI, LE on each of the camshafts.(R for right
bank, L for left bank, I for intake and E for exhaust) Right bank
camshafts are marked with one dot, left bank with 2 dots on the shaft
itself. To align the camshafts to each other each cam shaft gear has a
mark on it. Draw an imaginary line between the centre of the camshaft
and the centre of the pulley. The alignment mark should be between the
two along this imaginary line. The result will be that RI an RE will be
at the top of each gear. The same with the left bank.
there will be two highlighted or dotted chain links for the camshaft and one for the crankshaft gear, position cam dot/TDC indicator in the 12-O clock position, the two dotted links should be on ether side of cam dot, turn crank dot to the 6-O clock position and line up highlighted link with dot on crank gear, if timing cover is on, then make sure cylinder 1 is at TDC when the two links are at 12-O clock.
You didn't say which 4 cylinder engine you have, whether it is a single or dual cam engine? I am assuming since it is a station wagon it is the single cam engine.
On camshaft gear you should see a little arrow or pointer in one of the windows of the gear,it should be at the top and should line up with a dot on the head. The crankshaft pulley groove should be at the top and it should line up with a dot on the block or TDC/ 0 on the guage.
