So, I need to get my left side heads off....
So....I'm pulling things apart.

Background, '73 911E, but has a rebuilt 2.7, built by a reputable shop in the NYC area. There was an engine fire and the left side c
yliders injested crap and need serving. Right side compression is 175 across the boar, IIRC. I have fantasy that I can just do the left side, as this engine has very (sad to say) low miles, maybe 5K.
I did a 2.4 rebuild ages ago, so it's taken some time to get up to speed ..LOL

So far no issues until now. I can't get the rocker shafts out on exhaust #3, and #1.
On #3, the tension bold and cone nut are out, but the shaft will only slide so far and it just won't go any further. Not sure what to do there...

On #1, I can't break free the 5mm bolt, or the 8mm nut. THere's little space behing the cam housing to get a 5mm hex socket, so I'm using a shortened allen key, but no love. On the nut end I've tried my 8mm allen key with a 8mm box end on it's shaft for stability, but the hole is shallow in the nut and it just won't budge without seeming like it's going to slip out.

I assumed I needed to get the rockers off before pulling the cam..but, I'm not so sure now. It apears that I can back the adjustment far enough off that I can clear the base of the lobes and I could turn the cam to clear things as it removes?


So, thoughts?
A- I was planning on reusing the rockers and hardware, they weren't leaking and play felt great.
B-I figured I'd add the RSR seals just in case.
C-If I can't pull the cam and get the housing on the nench where I can have better access, are there tricks?
D-If I CAN pull the cam, should I even bother removing the rocker shafts on those remaining ? Or just put back in place.
E- I think proper tq is 18 ft lbs...how to measure? No way my tr wrench will fit! Tricks?
Thanks!
