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\r\n\r\n\u003cdiv style=\"overflow-x:auto;\"\u003e\r\n\u003ctable align=\"center\" border=\"0\" cellpadding=\"5\" cellspacing=\"1\" style=\"margin:auto;width:500px;\"\u003e\r\n\t\u003ctbody\u003e\r\n\t\t\u003ctr\u003e\r\n\t\t\t\u003ctd colspan=\"2\" style=\"text-align: center;\"\u003e\r\n\t\t\t\u003ch2\u003eSPECIFICATIONS\u003c\/h2\u003e\r\n\t\t\t\u003c\/td\u003e\r\n\t\t\u003c\/tr\u003e\r\n\t\t\u003ctr\u003e\r\n\t\t\t\u003ctd style=\"width: 50%;
