Gotta know, how do you do the motor plate? Do you have to use a WP gasket on both sides of the plate?

I am using the Hooker 2241 headers, they should fit just have to notch the frame rail a little. Once i get the motor back and get the headers installed i will post pics.

I used 2241 headers as well and they fit pretty well with the BMR K-member. I had to make one slight change to them on the passenger side because they hit the firewall on one tube. I know this is slightly off topic but the TH400 dipstick tube works really well from Mad Man for the big block. If you are just beginning this conversion you will really appreciate the items that just fall into place.

oh im sure the turbo setup would have run strong but i still think the BBC was a better choice. I lost a LOT of money changing setups when the turbo setup was pretty much done.
