Max Power 74 Report post Posted May 6, 2014 Why would they make oval port headers for a windsor application. No windsors have oval ports. Quote Share this post Link to post Share on other sites

69isfine 10 Report post Posted May 19, 2014 I have the Hedman ceramic with stage 8 header bolts in my car for the last 2-3 weeks. My 351w was stock. No issues so far. Quote Share this post Link to post Share on other sites
Max Power 74 Report post Posted May 19, 2014 the heads are edelbrock aluminum. I have RPM heads myself and the heads are square port exhaust, as are most aftermarket heads for Windsor applications, since most headers for Windsors are also square port. Are you heads ported or possibly Cleveland heads? Quote Share this post Link to post Share on other sites
DocWok 30 Report post Posted May 19, 2014 Make up a template of the header port out of paper or cardboard and place it over the edelbrock head, if it doesn't obstruct the exhaust port and it bolts up you should be good to go. Quote Share this post Link to post Share on other sites
