Sold: 32v Heads for sale, $325
Ok... who wants them... $325. I've got a set of 32v heads off a running M29/42 MY87 engine, compression was good and all lifters have been kept in their bores. They are complete except for the cams. I will ship these so it's first come first serve. Sold.

Another bump for a great price.
FWIW, I recently listed for sale a set of early S4 heads and got zero interest in them. I suspect that this is not a good sign for non-running or ailing S4's. The cost of repairing these cars keeps going up while the value of the car goes... ???
Best wishes on the sale.

Mason is correct the early heads have a rare tendency to crack. Porsche increased the thickness used longer bolts which is what the 3r is about. Fair to note that most 87/88 S-4s are still running around just fine with the early heads.

You know I wonder about a Reverse Hybrid, 32 valve heads on my 4.5 litre engine. Turbo 32 valves make considerably more power per PSI than 16 valve engines. And I'm in the midst of building a new inlet manifold anyway! Throw the distributor and replace with EDIC 8 ignition and the jobs just about done.
Any Thoughts?

These would be gold to somebody who sufferred a timing belt break. The valves alone would cost as much as this, wouldn't they?
The block would be interesting too, but timing is not right for me. Somehow I ended up with a complete set of 5.0 pistons to which somebody has apparently machined indentations for Euro
S valves. On the shelf for now.

That's what I did when I got my '85, 10 years ago. It was WAY cheaper to buy a good used head that to rebuild the exisiting. Worked out perfect.

Its just amazing how little value some of these parts have. I'd discount them even more but at some point it isn't worth the hassle of packaging them. If no one wants them they're going on the shelf as spares for my track car since I'm running the same heads on that engine.

Swaybar posted this long ago under another nom de plume. Maybe someone who wants to stay NA can put these on an 85/86 32v block and use those cams in these heads.
The total cylinder volume is 619.7 cc's, add the S4 piston
chamber volume of 75.3cc's to this creates a total volume of 695 cc's.
Divide this by the S4 piston chamber volume of 75.3 cc's yields an S4 static
C/R of 9.23:1.
The32V S chamber volume is 64.2cc not including head gasket. The S4
measured in at 67cc's. (25.4 piston/41.6 head) Add 8.3cc's for the head
gasket gives a total chamber volume for the 32v S of 72.5cc's. Take the 619.7 cc's cylinder volume and add the 32v S piston chamber volume of 72.5cc's yields a total volume of 692.2 cc's. Divide this by the 32v S piston chamber volume of 72.5 yields a 32v S static C/R of 9.55:1.
A little better then the S4, well within the bounds of the 10:1 +/- .4 factory spec, but still pretty far from the touted 10:1 max spec.
Now, check out S4 heads on a 32V S block: 41.6 cc head + 8cc piston + 8.3cc head gasket = 57.9cc total chamber volume. Add the 619.7 cc cylinder volume for a total of 677.6 cc's, divided by 57.9 = 11.70:1 static C/R.
For you forced induction fans, 32v S heads on an S4 block: 56.2 head + 25.4 piston + 8.3 head gasket = 89.9 cc's. Add the 619.7 cc cylinder volume for a total of 709.6 cc's, divided by 89.9 = 7.89:1 static C/R. Not much throttle response there.

Hope you don't mind me posting my heads since you sold yours... :-). I have a set from an 1988 for sale for $450 with cams and tensioner. Has to sell fast since I am looking at another project car... so I am entertaining offers.
