Head studs

[H440exconfused]

I am installing a new head gasket again in my 440.

The question I have is that stud head bolt fix everyone is talking about, do I have to install larger ones and drill everything and retap, or do they just sell a factory SIZE studs with a hight tensil strenght.

Thanks in advance

I found out the hard way after going though 4 head gaskets that the studs were coming out of te head and that they were streghing out from the heat and the high compression. The fix that we did was to get the 12mm studs from TC Racing and this fixed it. All that we had to do was to run a 12x1.25 tap (I think) down the holes and put the new studs in.
