It has been over a month.... and I've been busy finishing a few other client's heads.... OST-074, and OST-076 are water cooled 8V Porsche heads - one turbo, one n/a, and OST-072, and OST-073, lets just say... "more to come".............

but for now back to finishing up 071.

Had to share this image.........

The correct head gasket came in 5 weeks after order, installation went smoothly

I now do 6 passes on the head bolts, 2 @25, 2@36, and 2@48 (metal head gasket) Why do I now do 6 passes? I've found that after each pass, the center bolts are no longer the same torque they were, and as you go along the 2nd pass, they even up. With this method, on the 6th pass, you will likely only add turns to the center 2 bolts only.


with the head and block now as one, and the new Cat cams installed.

add in a newly powder coated inner timing cover, and a set of vintage HKS timing pulleys...

set cam timing ever so carefully....

All that is left is final assembly..... (this pic just before)
