Then using masking tape I covered up the out/inlets and the top camshaft area, I then gave the head a couple of coats of high temperature aluminium paint.

This is my record of the restoration of my 1977 Triumph TR7, I bought the car in 1983 for £1500. Over the four years of driving it I had got married, moved to a 110 year old cottage in need of renovation and given a new company car. The TR was parked in the garage (1987) at the end of the garden. I always joked saying "that one day I put it back on the road". Twenty-four years later (Nov 2011) that day has arrived - wish me luck.

Head assembly...
With the valves reground it was time to refit them and paint the cylinder head. Using a block of wood to protect the valve head they went in without any issues.
Then using masking tape I covered up the out/inlets and the top camshaft area, I then gave the head a couple of coats of high temperature aluminium paint.

Reseat the valves...
Using a valve grinding stick, I start with some coarse paste to remove the build-up of carbon and muck around each valve seats. Some values would have been in an open position for more than 20 years.
Using the fine paste next to achieve a matt grey finish on the head and the valve face will ensure a tight seal.

Decoking the head...
With the head stripped it was time to give it a good blow through - using my Karcher pressure washer in every hole removing any build-up and old antifreeze that had turned to sludge. Then with some degrease solution, fine wire wool and brass wire brush I de-coked the build up of carbon from the chambers.
While doing this a had the valves and springs in the ultrasonic cleaner. After 20 minutes the carbon around the valves had softened up allow me the gently sharp if off and a quick go with a wire brush in my drill to remove any remaining bits. One set at a time so they wouldn't get mixed up.

Engine breakdown... pt11
Borrowing a valve spring compressor from Dick (many thanks) a member of my local Thames Valley TR Register Club. I removed the inlet and exhaust valves bagging them in pairs with the spring, collar and cone type collets.
The valves felt nice a tight in the guides and no signs of damage other than build up of carbon. Next stage to clean-up the head and re-seat the valves.
