L31 engine swap questions

[memo43]

Thanks for the corrections
I was a little groggy when I submitted my post.
its the bolt holes on the stock manifold that isn't tapped for the new engine.
it's only on the passenger side head
the stock manifold is set up for the rear most bolt hole.
the vortec motor does not have this hole tapped.
I have all the bolts installed minus the very last one.
Wishful thinking that I don't have a leak there. although I plan on getting the ram horn later this week an sending it off to have the exhaust re done.
hopefully I will be able to get some pics posted later today
