Head gaskets stuffed

[pistolpedro]

So after nearly 7 years she blew a coolant hard line at the back of the motor and after fixing that it turns out the head gaskets are stuffed so in to there I go. Pricing up stuff but need to know of its the go, just for an N/A but I wanna do it right while im putting my mechanics kids thru college lol
So need a head bolt set, found these on trademe, any good for an N/A? I've heard stories about shit ones!

Also rather than the heads that are there which may be cracked and will have to be refurbished I also found these which they claim are straight and have been visually crack tested.. Should I....?
