1990 toyota 4gfe questions

i'm pulling the head off of my friends car because he over heated the thing.

i dont have a book. he is super cheap. so thats why i'm here. i want to know what the timing marks for the cams are suppose to look like, also what is the torque of the headbolts and cam bearings.


thanks. i guess this engine was used in a lot of cars and geo cars as well.

thank you all.

Looks to be a dimple in between two timing gear teeth to mark the TDC for both camshafts. Here's a link to a repair guide for the timing belt removal:

There should be links as well for removing and inspecting the heads and deck. Good luck...your friend owes you and us!
