Thanks

yeah thats what I do for threads I dont have an actual chaser for. that and some acetone and compressed air.

Looks pretty similar to the ones I did. I'm in the middle of my rebuild.

Thanks guys ^

Anyone else got input on this?

How would I know it's clean enough and ready to start putting the head bolts in, I guess if no gunk comes out any more .. or..?

Thanks

Those should work. Looks similar to the ARP chasers I have.

And yeah, just keep working them through until nothing comes out.

You should be able to shine a light down in there and see if the threads are shining too. Then finish it off with some compressed air.

Thanks team, finally can get to putting my car back together! last step to cleaning it up.

Chased em trough quite a few times some bolt holes seem not to be filled with crap? N they spin down fine without to much resistance and come out with minimal or no gunk.. just wanna make sure it's fine to proceed ?

Not tryna crack nothing

I back it up with a nylon rifle brush in my cordless drill, spin slow with a little light oil in the hole and you can pump them clean. Then dry them out with some carb cleaner and some air through a small piece of brass tube from the hobby store.

I cut a groove, put the tip in some automotive grease, went in and out multiple times, and poured some thinner down the whole to break down the grease then blow it out with compressed air. Time consuming but works great

Might aswell update here on the build.

Cleaned all the head surfaces, piston heads and bolt holes time to re assemble!

I put in the new trays and lifter trays and head gasket on the passenger side it's time !
