Like New Heads. Only used for engine break-in (about 550 miles). For use on a Ford 302.
High density cast iron heads to be the most powerful head for 5.0 Fords.
When it comes to high performance replacements for factory cast iron heads, which flow a substantially larger volume of air than any OEM Ford head. Big bolt-on power!
These heads are also 50-State emissions legal factory replacements.
ALso, a rebuilt 30 over 302 short block - ran great but flattened a cam lobe...so, needs cam and lifters.
