i was wondering how reliable would using twin head gaskets be? any problems?

Dont put in double head gaskets, you will get problems you don't want, get a thicker one instead.

Why you want to for, you trying to lower compression or did you get everything machined and trying to get back to normal.

copper head gaskets go up to 90thou which will be enough for your problem they cost around 175 a pair and dont pose any real issues exept that your manifold may need extra gaskets to bring it up to spec, 2 sets of standard 40though gaskest would cost that if you brought decent ones.

The flame stays in there as it doesn't have complete burn.So when next compression takes place it will detonate or fire too early..Thats the reason why also 4 valve heads can get away with high compression on blown engines....
