HEAD GASKET PROBLEM

[napalm9884]

I'm running 100 HP Nitrous on a modified '68 ford 289. I blew out the stock head gaskets, they couldn't contain the increased cylinder pressure. There are no o-ring grooves machined in the head. Should I go with fel pro? I've heard some bad stuff about their head gaskets. Any info would be appreciated. Thanks.

Fel-pro has gaskets specifically made for nitruos applications.stock gaskets won't do.
I don't believe machining grooves will be needed.
