Hugger Exhaust Headers Black For SBC 265-400 V8 Straight Plug Style

The "Block Hugger" headers are designed specifically for 1955-up Small Block Chevy 265 283 305 327 350 383 400 V8 engines, with the exception of certain models from 1971 to 1987. These headers are meant to be used in tight spaces where long tube headers are not feasible due to clearance issues with the steering and cross-member.

The headers feature a 3-bolt mounting style and have been optimized for 5.0L (305ci), 5.3L (327ci), 5.7L (350ci), and 6.6L (400ci) engines. The tubing has been carefully designed to provide optimal performance. The inlet size is 1 1/2", and the outlet size is 2 1/2".

These headers are constructed from steel and have a black painted finish. The head flange thickness is 3/8" (9.5mm), and the pipe thickness is 16 gauge (1.5mm). The package includes all the necessary items shown in the picture, such as bolts, gaskets, and a pair of reducers, making for an easy installation.

It is important to note that these headers are designed for straight-plug cylinder heads, and users may encounter interference problems with angle-plug heads. Professional installation is highly recommended, as the instructions are not included.

In summary, the "Block Hugger" headers provide a reliable and space-saving solution for 1955-up Small Block Chevy V8 engines, with the exception of a few specific models. The thoughtful design and inclusion of all necessary components make for a straightforward installation process, though professional guidance is advised.
