Frequently Asked Questions

Do these heads fit all first-gen 5.9L 12-valve trucks (1989–1993)?

Yes—these listings target 1989–1993 VE-pump 12V applications. Always verify ESN and part-level details on the product page.

Should I upgrade to head studs on a stock truck?

OE bolts can work on stock boost, but head studs are smart insurance for towing, higher boost, or performance use.

New vs. reman: which should I buy?

New castings eliminate core concerns; reman heads can be a cost-effective option when properly rebuilt and pressure-tested.
