The lightweight heads are cast from A-356 aluminium alloy with a large choice of engines, for SB \u0026amp; BB Chevrolet, LS Chev Holden Ford SB 289-351W, 302, 351 Cleveland 2V \u0026amp; 3V \u0026amp; BB FE, and Chrysler SB \u0026amp; BB. They have phosphorous bronze valve guides, and ductile iron valve seats for use with unleaded gas. They're also end-milled and drilled for accessories. The fully assembled heads have stainless steel valves, high performance valve springs, 7 degree valve locks, rocker arm studs, and guideplates. Perfect for your mild or high performance hot rod.\u003c\/p\u003e\n    \u003cp\u003eNote: We suggest using Proflow Head Bolt Stepped washers part number PFEAHF-HBW. Proflow head bolt insert washers are designed to be used on Ford Windsor cylinder heads in applications where you have 7\/16\" head bolts being used in 1\/2\" bolt holes. This stops head bolt hole distortion on aluminium heads when using 7\/16 bolts on 289 \/ 302 standard Windsor blocks.\u003c\/p\u003e\n\n    \u003cdiv style=\"overflow-x:auto;\"\u003e\n
