These headers will fit close to the block and exit to the rear.
The equal length tubes have a 'pin' where they contact the heads or header flange. They can be easily cut off with an X-Acto knife.
Bolt heads are on each side of each tube where they would bolt to the heads.
These are made for a BBC but I find most exhaust ports are the same distance apart for a HEMI engine.
