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. 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 the head bolt hole distorting 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        \u003ctable align=\"center\" border=\"0\" cellpadding=\"5\" cellspacing=\"1\" style=\"margin:auto;width:500px;\"\u003e\n            \u003ctbody\u003e\n                \u003ctr\u003e\n                    \u003ctd colspan=\"2\" style=\"text-align: center;\"\u003e\n                        \u003ch2\u003eSPECIFICATIONS\u003c\/h2\u003e\n                    \u003c\/td\u003e\n                \u003c\/tr\u003e\n                \u003ctr\u003e\n                    \u003ctd style=\"width: 50%;
