Nope. That is $587.99 for the head and $125 if you do not provide a rebuildable core.

Realistically, if your head is serviceable, it should cost you in the neighborhood of $250-$300 for someone to go through it for you.

There are new, aftermarket castings available for $500-$550, I think. Everyone I know of who has used one has been happy.

Good Luck,
Michael
