Bad idea, skimming the head. Now the face is flat but the top side is still warped, so cams are bent.

What do you mean about the clutch pedal? Why is your foot anywhere near the clutch pedal while revving and driving?

No-eyed Deer - I had never even thought about your bent cam point !!

Think i will call the engineer and see what he says - just me being inquisitive .

Fitted to the car is an OSGilken multi plate clutch and in traffic if i sit with it depressed in gear it gets hot and will judder when next used !

SO I return to neutral every time i am in traffic with my foot resting on the clutch ready to go . This is when i found the clutch pedal pushing my foot up when i revved the engine .

Also the brake servo pipe is SERIOUSLY under pressure / almost solid feeling when the engine is running .

I was thinking maybe there is an issue with the AAC valve as the engine rev`s have also increased after refitting the head .

Bloody Hicas started to try and kill me today as well , keeps pulsing and trying to correct the steering wheel angle to straight in a bend ?? NOT going to lock out as when it works it is so much faster on the road - have heard that not that good on a track though .

found the issue - the O ring at the rear of the clutch master cylinder that seals the servo unit to the master cylinder was split in half and so letting air in .

Found part of it sticking out of the vacuum pipe that connects to the 1 way valve and then AAC valve .

Lucky break as would not have thought of that !

      Yes, I know🙄 but the sequential is not in my budget... don't want to reduce power neither, so looks like I'm stuck in the rabbit hole🤣

      You’ll be very upset when you bust that too not to mention the gearing totally sucks. Don’t do it.

      Is the panel filter one that is oiled? Have you ever cleaned or touched the AFM?

      So.... the K&N air box thingo was too big, ended up gifting it to a mate, well, by gifting it he actually supplied food and beer at the pub,  which was nice, as it will not sit on a shelf in the garage for the next 10 years I did trim up some of the existing stuff to neaten it all up and gave it some wrinkle paint, unfortunately it currently has a used and abused mish mash of different types of hose clamps, 4 big fat T bolt type (shit), and a few normal clamps of vairing sizes and brands, but..... only until the 6 constant tension black worm clamps that I ordered from EFI solutions turn up next week Currently the current hose clamps are triggering me hard, LOL Is this the final version, probably not, I really want just 2 silicone pieces, a straight bit of silicone from the filter to the MAF is easy and will happen as soon as I head into Just Jap tomorrow, the problematic part is a 30° silicone bend from the MAF to the TB that I can connect the engine breather from the head, I found that there are bulk head fittings for boat bilge pumps that should work, but until I can get a 30° silicone bend the alloy pipe, and the 11ty thousand hose clamps, are there for the foreseeable future 4 hose clamps are golden, 6 are grudgingly acceptable, the 8 currently holding it all together is just taking the piss    I've also ordered 60 more retaining wall blocks for the front yard, I mis-gonculated the height that was required to get above the base of the Photinia's (red robin's) that are the hedge behind the front fence, currently it is 2 blocks high, and about 1/2 a block short, so going 3 blocks high will be above the base of the red robin's, and allow some room for mulch
