Getting ready to finish up the 351, few gaskets left to obtain.

Two of the gaskets are the header gaskets. Which is a better choice, the old style aluminum covered paper gaskets or would it be worth the extra coin and get the thick aluminum pair?

Also what's a good choice for fasteners?

Thanks gents.

I had wonderful luck with these:

The difference is in those header bolts that don't back out.

Those look to be a good set. I haven't had a lot of luck with the old paper like ones, usually had to stack them and constantly tighten the bolts. As Ryan said, get the type of header bolts that don't back out, otherwise plan to recheck them constantly for quite a while, then they might finally stay... The expansion/contraction cycles of heating and cooling is what loosens them.

I went with the metal gaskets and no locking bolts. I do have to retighten every week, they are not loose loose, but definitely need to be re-torqued. Easy enough with all the room, but would suck if in a tight space.

Just for comparison, I paid extra for the non-loosening bolts and never once tightened them for 2 years with no leaks.

I think I will switch Ryan after your post, just makes sense, no issues
