Buick Apollo 5.7L 1973-1975, Graph-Flex Header Flange Gaskets by Percy's High Performance®. Persy's High Performance makes exhaust manifold and collector gaskets that will withstand the temperatures generated by turbocharged motors, and exhaust gas temperature monitors to see exactly how hot that is.
Fitment notes: Fits Models with Small Block Engine.
- Modified engines have hotter exhaust
- Better materials help seal poorly-mating flanges better.
Highly modified engines, turbocharged, supercharged, nitrous or fuel-burning ask more of exhaust system components, which requires advanced materials. Persy's exhaust gaskets will seal better, longer and more reliably. In addition, they have the technology, in the guise of thermocouple probes and EGT gauges to let you track exhaust gas temperatures in real-time.
