No. they are different head designs.
Pontiac 455 headers generally do not fit a Buick 455 due to differences in the engine's exhaust port locations and bolt patterns. While both engines are part of the General Motors family and share some similarities, the specific design and dimensions of the exhaust manifolds and headers vary. If you're looking to upgrade to headers for a Buick 455, it's best to choose headers specifically designed for that engine to ensure proper fit and performance.
Not without serious modification, but anything is possible if you have enough money for a conversion.
Yes, a 1969 455 Buick engine can fit into a 1985 Buick Regal, as both vehicles share a similar body platform. However, some modifications may be necessary, including adjustments to the engine mounts, transmission compatibility, and possibly the exhaust system. Additionally, the 455 engine is larger and heavier, so it's important to ensure that the suspension and brakes can handle the increased power and weight.

You'll need to ensure that the engine mounts and transmission are compatible, and may require custom headers or exhaust modifications due to space constraints. Additionally, consider upgrading the cooling system and suspension to handle the increased power and weight of the 455. Overall, with the right adjustments, the conversion can be a rewarding project for performance enthusiasts.
A 455 is probably the easiest to find cheapest . I bet cars inc have motor mounts for the swap Do not put a Chevy 350 in there or I will never ever ever speak to you again . You SHOULD put a 430 C.I. 7.0L Buick motor in there , that's whats meant to be there , 360 bhp & 475 ft lbs of torque.
If you have the MONEY and the KNOW HOW, You can put whatever you want in there.But as far as it just hooking right up to everything and having no problems. NO.
The 455 will fit. The transmission might have a shorter tailshaft, though.
I put a 455 in a regal.. and it was a snap. get the right mounts, i used factory steel from a 73 centurion 455. then used A body headers ,u half to drill new in the frame ... noithing will line up so dont bother trying.if all goes well for you, the reward is cant be be beat
