There are photos of valves that have been cut open that reveal the center hole was drilled considerably off-center resulting in inconsistent wall thickness with one side being much thinner than the other. Recutting the counterbore also allows you to control runout in the counterbore and concentricity with the valve guide. If those numbers match the engine and frame came from the factory together.

The stones would wear or chip causing me to redress too often. Anyway, all this to say I meant to respond to this thread some time ago, but.
Its and valves were controlled manually; the latter was with a hand lever rather than a foot pedal. The throttle is a lever mounted by the steering wheel, like a tractor. The magnets spin past each of the 16 coils and must have the same clearance to ensure that a strong and even current is induced, providing the ignition power. Wheel size front Wheel size rear Tyres front 30 x 3 Tyres rear 30 x 3. As my car is a 1927 model, it is fitted with a starter. His current automotive passion is divided between his Mazda Miata, 1976 Mini Cooper, 1920 Model T Ford, and 1971 Fiat 124 Spider. The crankshaft was lifted and the shear point examined.

I got the block out of the shop and looked close and checked things out and it could use knurling and seat fixing.

It was quite fortunate that a friend from our club was in town and had brought his magnetiser with him. Some production engine rebuilders as well as custom performance builders use a Spintron machine to check compression and valvetrain operation in a newly assembled engine.
The first thing I met, with the inspection cover off, a collection of babbitt filings collected in the number one dipper space. And if the seat is too wide, there may not be enough pressure to provide a tight seal. I have a set of Neway cutters that have cut new seats several T club members blocks. I have lent them to several T guys and every one seems to like them. Knocking out some of the babbit here showed that it had been correctly poured, although it was quite thin. Find a good one, preferably one with a Newen Contour machine and let them handle it.

In my case, particularly as the head gasket had leaked near two of the problem threads. Bob By on Monday, March 03, 2008 - 10:54 pm: Well since this thread is still active,maby you all can shine some light on a discussion I have had with the fellow that ground the valves for me. Philip Carrasco at Tucker says seats may require anywhere from. I always use modern 351W Ford exhaust valves and Ford 8N retainers. For one valve job on one V-8 it will probably be less expensive to have it done rather than buying the tools.
Unfortunately for us, three of the four rods were within a few grams of each other, not needing any work, but the fourth, the lightest, came in at nearly 2 ounces lighter than all the others. I went with Ford 8N tractor cups and keepers, based on a suggestion from this board. With mine removed I discovered a few things. For that reason, replacing valve seats is often necessary when reconditioning aluminum or cast iron cylinder heads. What is the advantage of using stainless steel valves vice standard chev. Not uncommon, but it seems my T had succumbed to the stresses of driving in modern traffic.
There is no oil pump — all lubrication happens by splashing the crank through the oil pan, drenching the three main bearings, the cam, and the lifters with oil. Except when I am needed to extricate someone's tit or dick from being mangled in the wringer. I want to do as much on this project myself as I can more or less for the learning experiance and of course to save a buck if I can. But more interference fit is usually needed in high mileage heads or ones that will be subjected to high horsepower levels. That includes cylinder head thickness, valve guide clearances, concentricity and perpendicularity.
This includes checking for cracks especially around and near the valve seats and checking the deck surface and cam bore for straightness. Now I am just an attorney, not good for much. Coated Pistons The pistons have returned from their treatment and as you can see are now sporting both a white ceramic crown coating for better heat dissipation and the piston walls built up with a teflon coating. It's easy to just ream the guides to an oversize but I also then knurl the guides to give better oiling yet maintain a tight clearance. Thanks Bill By on Thursday, February 05, 2009 - 06:22 pm: I have always used new stainless valves. As the stone wears, it needs to be dressed. Many aftermarket seats have a bevel or radius on the outside lower edge to make installation easier.
