also, install a new valve oil seal.. and grind the valves...

Not sure (please check it)Where did you get the head gasket on your block?
Not sure (please check it)
but the head from 1.5F has the same holes as 2f. I just use a 2f gasket for the 76.
Also PO used same type of gasket, and I assume he is drive it.
check here info:

I find an old gasket kit (no Toyota) on eBay, it made in Japan.This gasket?? Looks unusual… Toyota?
Definitely not Toyota. Cheap Stone gasket by the look of it.This gasket?? Looks unusual… Toyota?

I start work on the engine just in the first year of my Fj40 project.
After spending 3 years on this project ... I have learned a lot.
If you ask me now,... I will only buy from Toyota or a local vendor who has a reputation here.
I don't want to redo it in the near future...

P.S ^^^^ look in Jim icon here I remember he has a thread here: how do not rebuild engine"
edit: I find it How not to build the 2F - https://forum.ih8mud.com/threads/how-not-to-build-the-2f.563170/
Well you can figure out half the puzzle if you look at the cylinder head number cast into the head. What is yours?I don't know for certain... I picked up the engine recently not knowing the year. I cleaned off the SN (2F 037791) and from the MUD Spreadsheet determined it was a 1975 Engine. I'm going with the assumption it's an open chamber with domed pistons. I'm just wondering if I should be thinking about trying to find a closed head. I can probably swap it for one. I haven't started pulling it apart yet and I might not do so until next year, so I won't know for a while. Just thinking ahead.
BTW, I'm in Tempe, just north of you.

I pulled the head. It’s a 61030 with domed pistons. TBD if the head is good (no cracks) or if the block is going to need to be bored. I was just trying to understand the options if the block did need to be bored given that the domed pistons in a O/S are NLA to my knowledge.61030
Bumping your compression (within reasonable limits) is a great way to increase low end torque.
If domed pistons are NLA as mentioned I would run the closed chamber head if you have one. If you run the closed chamber head and flat top piston you can still mill the head to achieve more compression but you should calculate that out. CC the chambers and know your compressed head gasket thickness. The machine shop should be able to help you with that.
Keep in mind that if you go too high with compression, your octane requirements go up even with retarded timing. So find out the ideal compression ratio for your intended use.
If all you have is an open chamber head and all that is available is flat top pistons you will loose compression and performance unless you bring compression back up by milling the head or find domed pistons. It will still run with the lower compression but you will notice the loss of performance.
What head do you have?
