Proflow does not sacrifice quality for a low price--you get both with our aluminium cylinder heads. The lightweight heads are cast from A-356 aluminium alloy with a large choice of Engine, for SB & BB Chevrolet, LS Chev Holden Ford SB 289-351W, 302,351 Cleveland 2V & 3V & BB FE, and Chrysler SB & BB, 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 the head bolt hole distorting on aluminium heads when using 7/16'' bolts on 289 / 302 standard Windsor blocks.
