Proflow Cylinder Heads, AirMax 170, SB Ford 289, 302, 351W
Proflow does not sacrifice quality for a low priceyou get both with our aluminium cylinder heads. The lightweight heads are cast from A-356 aluminium alloy with a large choice of engines, for SB & BB Chevrolet, LS Chev Holden Ford SB 289-351W, 302, 351 Cleveland 2V & 3V & BB FE, and Chrysler SB & 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.
Note: 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.
