Lakewood Aluminum Replacement Bellhousing for Small Block Mopar

I have a 67 Barracuda with a 273 Commando and 4 speed. The existing clutch arrangement for the 273 is a 9.5" clutch with 9.5" 122 tooth flywheel. I'm looking to mothball the 273 and replace with a 'stock' looking iron headed 416. I need to go to the larger 10.5" clutch which requires a 10.5" bellhousing. My question is, does the Lakewood 10.5" alum bellhousing bolt straight into a 67 Barracuda? Will it provide enough clearance for Doug's headers D453's?

The factory 10.5" Mopar bellhousing is part number 2892482 for such a swap, but I can't find one at the moment. Thanks.

The Lakewood bellhousing I can get my hands on is listed below:
