Cometics are definitely fantastic gaskets. Using their head and intake gaskets on my 408 now. I've used the 1 piece reusable style oil pan gaskets on other engines with real good luck so I thought I'd give it a go if someone could confirm it actually fits an LA. A couple yrs back Summit and JEGS had 1 listed that supposedly fit an LA but some guys here tried it and it didn't fit right. That's why I thought I'd ask here first.
