    I did a compression test and that came out 140-149 on the cylinders. I checked the maf and found the plug had come out. Looks like I need a new maf

    That’s great you found a relatively simple problem to fix, way better than if you were down on one cylinder!!

    I’m not planning to. I’m just going to get one off a mate until tuning time.

    Nice work, messy job isn’t it.  I guess it gives you the chance to clean it up a little whilst you can get at it?

    its actually not too bad apart from the alternator bracket. Going to be fun getting the old graphite head gaskets off. I think im going to use the gasket remover spray. I have the lifters soaking in oil. I have done the valve springs in one head, i will do the other tonight. I still have to drop the sump to do the oil pump then i can do the timing chain.

    Does any know if it is worth doing the trunnion kit?

    I was highly recommended to do it.  If one let’s go, and the needles go into the sump you are in for a world of pain….

    Nice, they were actually pretty straightforward to fit, just be methodical!

    Having access to an arbor press helps a lot too.

    I recently installed a trunnion kit.
    Use an arbor press or a bench vice, it’s pretty straight forward once you get a rhythm going.

    It definitely makes the valvetrain much quieter in my experience.

    I saw a video of using the vice to press them in.

    Do me a favor bro, put some tape over those inlet ports!!  I shudder every time I see a pic of them open like that, one washer or whatever accidentally falls in there that you don’t notice and “boom” on startup :negative:
