Agreed. Unless the 351W heads are close-chambered, which they're likely not, you're much better off with the ported 289 heads. They won't flow fantastic compared to an aftermarket head, but they'll be much better than stock. The stock 289/302 exhaust ports are horrible.

an e7 is slightly better than a 289 for flow, but have a larger combustion chamber so your gonna lose compression.
if you want to use something late model look for the gt40 heads 96-97 5.0 explorers are the best place to find them, or 93-95 cobras and 351w lightnings
