There's no benefit to a non-girdled head except price, and it's not a place you want to save money. Get a girdled head, especially if you are upping the compression (and if you're not, what are you buying a head for?!)

Cracked Cylinder
I wouldn't necessarily say high compression or overhead pipes are the cause of cracking since one of the girls I ride with just cracked her cylinder 2 wks ago above the front 2 bosses where you bolt the cylinders down. She was running a B-pipe limited. She wasn't jumping or anything like that so I don't think it has anything to do with weight of the pipe but maybe just a casting flaw. She also runs a stock head with stock compression.

porting weakens the areas that are known to crack on a 61x cylinder. however, a non-ported 61x cylinder with a b-pipe and stock head can crack. ive seen it. its just not worth running a non-girdled head.

Is the 62t cylinder prone to this also?
it is a beefier casting right?

That is a weak point of the 61x cylinders............ Some will crack, some wont...... But, if you are going to ride hard, why take the chance.

usually on the front Right above the corner bolt that holds the cylinder down.

Sooo....
when adding a B-Pipe, it is also a good idea to add a girdled head or you may be asking for problem.
I've been saving for a B-Pipe, but it sounds like I should first replace the stock head and add a girdled head.

I plan to wrap my cylinder in duct tape.

Once they crack all the stress should be relieved so then I would imagine you could weld, re-surface the bottom cylinder mounting surface and you shouldn't have to worry about it again. My buddies was done with just JB weld and it's been holding together fine.

the 62t cyl has added some "support metal" right where the 61x cracks. they are less prone to cracking.

The B Pipe actually puts less stress than the OEM Pipe..............
