So the original bolt threads got a little messed up due to backing out part way so I need new ones.

1st - The correct size is 7/16 - 20 LH correct?

2nd - ARP / Ratech / Mr. Gasket
Normally I go with ARP but why are they 70 dollars compared to 15 for each of the
others? Recommendations?

Nothing wrong with OE--ARP is good, but probably overkill for street use.

Thanks for the OE part numbers. Summit racing had Mr Gasket or ARP as the only choices. $14 or $75 respectively. $35 for the OE from RMS seems like a good compromise. I'm going to check the local dealership tonight to see if I can get them for close to the same.

I've always been a little weary of Mr. Gasket parts as they seem to make every for everything. They're like the Wal-Mart of Random Auto Parts.
