Proflow's composition head gaskets are recommended for stock and mildly modified engines. They're available in a variety of bores, compressed thicknesses and volumes for fitment on specific vehicle and engine applications.

Note: Black gaskets are usually of NBR material (Nitrile Bonded Rubber) that have a temperature rating up to 108°C & our blue Silicone gaskets have a temperature rating up to 230°C giving a more stability over a broader temperature range
