Designed for all manifold applications for 289/302/351W engines with the following cylinder head applications:

M-6049-L302/L303/X302/X303/X304/X305/Y302/Y303/X306/X307/Z304/Z304A/Z304D/Z304DA with or without EGR

This gasket has the synthetic rubber Fel-Pro print-o-seal (Fel Pro Inc.) bead around ports to provide much improved sealing. Gasket material is listed as 0.070" thickness. Has the model number 1262S & R1 stamped into the gasket! I have measured the port to be approximately 1.28"x 2.175" through the packaging. Excellent quality. Should help with those cracked intake gaskets. Larger port openings for performance and ported heads/intakes.

note: It is recommended that with the Ford Racing race-quality gasket kits you use RTV sealer or production end seals.
