Not much to report. Using Wilson as daily transportation. No "fun runs". Keeping expenses low so I can take a 2 day Autocross course at the end of the month from these guys: http://www.soloprodrivingschool.com/

"here we are again". This all started because I over filled the oil sump & blew my cam housing gasket. Lesson learned. Upon repairing said gasket One of the last bolts I went to torque stripped. Tried repairing with a Heli-coil but it didn't take. I just cancelled the weekend driving course. Hopefully they'll refund me my $330. Bugger.

Wilson's Thread as he arises from the dead.

Got my rebuilt head from the machine shop. Took some comparison photos of my other 8 valve head.

The most important improvement is the turbo valve springs.

.030" shaved from the bottom. Like Ohio Tom says "improvement across all rpm range".

This is a factory Porsche intake. Notice the lumps on the interior wall from the casting.

View of the "street port" head. Exhaust angle.

As seen with exhaust manifold gasket.

So it is what is it. I had given them a budget & said do what you can. I was hoping for more extreme measures... and wanted to have the valves undercut. Not sure why they didn't do that... but they also came in under budget. I *think I should be sitting at 190 flywheel horse power after all is said. Perhaps I can find a dyno place this fall or winter to end my curiosity.

The plan is to clean up my messy garage. Then clean out my cam housing/camshaft. Advance the cam 1 tooth of the belt & retard 2 degrees with an offset woodruff key. Set the cam on the new standard thickness gasket & check for valve to piston clearance.

Cleaned out valve reliefs... not cleaning out carbon otherwise, what's the point? Modelling clay in full effect.

These aren't easy to find. Valve train checking springs. Never even heard of them before. When checking for valve to piston clearance, the hydraulic lifters aren't charged full of pressurized engine oil as they would be under running conditions. And when you crank the engine over by hand to check for clearance, you'll get a FALSE reading because the lifters will bleed out against the very stiff valve springs. So you pop the super light duty test springs in & not compress the hydraulic lifter as much, resulting in a much more accurate reading of the modelling clay.

Sorry for the out of focus shots. Camera is acting weird. This is my first time removing installing engine valve springs. I'm wearing a face shield. Did you know 10% of loss of vision incidents are caused by self?

In photo: I have compressed the springs & with the help of a magnet & small flathead screwdriver & pick out the retaining wedges.

I am only checking clearance on number 1 cylinder, so only 2 checking springs are used & 4 head stud nuts are used, with very little torque. No gasket is applied for testing, as I will add the compressed gasket thickness of 1.1mm (0.043") to the equation later.

Internet wisdom suggests compression ratio will be about 10.9:1 give or take.
