Any one know what the fitted valve spring hight for a short stem AEG163 Cooper S head is?

So when some joey comes on here about how his 16v turbo vauxhall is great compared to ours, he can be given the 'bird'...

Damn.

I was only looking at the page in Vizards yellow bible on Sunday as I was selecting old springs to rebuild the van's cylinder head.

I'll be in the garage later where I use my book so will check for you - I can see it now !!!

Looked in there and everywhere else, lol. Visard states a spring load checking hight which just so happens to be the same load on a closed spring. Free length of the outer spring is 1.74" with a closed valve length at 47lbft load of 1.2" ish(off the top of my head)

Problem is the springs supplied are the wrong ones and there are no caps or retainers, so its gone back to the customer just with new seats, guides and valves with a recomendation to fit the correct double springs. Ideally we need a valve stem fitted hight. The springs we had were singles and the load check looking at visards book make them out to be 997 Cooper springs, not Cooper S springs.

All because some one wants to keep it as original as can be :)

Sprocket.

Checked Vizard. Indeed, it doesn't give a fitted height in the table but does say the fitted poundage is 47 lbs as you said.

So, I measured my fitted double S's on the van tonight before bolting the refurbished head back on the newly prepped block (yippee - making progress at last !).

I measured 1.425 in compressed fitted height from base of spring platform to top of outer spring (ie the underside of the top shoulder on the retainer).

I have another set of used S double springs if you or yer man wants them. They should get you out of a hole but they are used if yer man can put up with that.

Why not use the same as a 949 head if those are the springs you're using?

Mine gets in the way a bit, but only when it is up. If it is down it does not cause a problem.
