timing marks and cam position

[mista_max]

I'm in the process of cheking my valvle clearance. Found timing mark for T1 , as shown in pic below ( sorry for the size don't know how to resize). When I check my #1 Cylinder I expected the lobe to be pointing face up but they are as shown on the second picture. Am I doing something wrong ?

you need to upload your pics.

When I see the timing mark for T1 should I be seeing the cam lobes pointing straight up for Cyl #1 ?

try turning the engine 180? so T1 shows again. i never use the timing marks honestly i just rotate the engine until the valves I want's cam-shaft's lobes are straight up.

i am not sure about what i am about to say , correct me if i am wrong. the firtst cylinder in the gen 1 is left rear and not the front left.

You are correct George! The cylinder orientation is as follows:
Front
2 | 4
------
1 | 3
Rear

No need to use flywheel marks. Just point the lobe straight up from the buckets.

I will add. You are not on the correct line if you were going to set the cam anyway. You would be on the line seen just to the left in the picture. Also, you would not go by the lobe orientation. You would verify the large or small holes (depending on which head) compared to the casting mark in the outer cap.

If setting up cams like newly installed or new engine this is really important.

If lashing valves alone just go with the cams at "rabbit ears position" for the cylinder in question, don't worry about the crank marks.

b/c on the 3 valve jobs i've helped with we've done it that way.
