Flat top or dome

[Idok]

Yes, resistance to deto is one of the most important reasons for a FT piston and this is partly due to less surface area and the effect the squish design offered by a FT. I cut my domed pistons with a bandsaw and polish them with a belt sander. Is this the best method?

sure! then just get an 85.5 or 86mm drill bit (hole saw works well also) and go to town on the cyl!

i also rec'd a BFH and a chisel for those hard to reach spots while porting!

#.0 I don't understand what you mean by lower tr. port timming. If you have to deck the base of the cylinder then you are doing so to lower the port timmings back to a workable range and when decking the base, doesn't that lower all ports the same amount?

Most of the flat top engines I've seen built are milling down the cylinder tops.

Your right that method would work for building a flat top engine but you would have to remove the sleeves to deck the bottom of the cylinder and the sleeves would have to cut down at the bottom.

You're joking... right?

Yes, it was a joke statement a friend pm'd. I had to put it up. .
