flathead refresh

Even if a .005" oversize piston could be found you'd need to have the cylinders opened up for proper fit since the unworn portion at the bottom would have no clearance. Better at that point to do a proper rebore and fit commonly available oversize pistons. Yes, if taper is minimal you can ream the slight ridge at the top, hone and fit standard rings. Don't forget to closely inspect the ring grooves in the pistons for wear and excessive side clearance...it happens quite often. If all looks good and taper is less than about .007" I've had very good results with new rings, valve job and proper clean up. I've done a lot of engines that way over the years and all ran a long time with no problems.
 
I think the presense of this Ford publication should shed some light on the subject at hand. I think the foreward tells the story and I like the last sentence in particular. I have refreshed perhaps 6 of our flatheads using this book as a guide and they have all come out with very satisfactory results. I totally get that this type of 'overhaul' is not for everyone, but it is clearly a viable alternative for the V8er on a budget or just wanting to have some gool ol' fashioned fun with their vintage ford vehicle.

When rebuilding your engine, one thing will always lead to another.

If you want to rebuild your engine the best way is to remove the engine from the car.
It will be well worth the effort and give you piece of mind knowing there are no chips of metal or valve grinding compound reminging in the engine that could cause massive damage and undo all the work that you did.

If you want to rebuild your engine for best results, the best way is to remove the engine from the car. It's not that difficult and will give you the chance to check the flywheel, clutch, pressure plate, throwout bearing, etc.
