well, i cannot speak for patriot products for GM, but i know of 2 mustangs who needed engine rebuilds because of patriots dropping valves only after a few hundred miles of driving after they were installed… they are notorious for it…in the mustang world that is…if they put out garbage for one make/model…im fairly sure they do the same for others. You get what you pay for definitely applied to heads.
as for head choices on mustangs…its pretty much the same still…patriot sux, VT is going down the tubes as we speak, and fox lake is where its at…however, im puting nearly 500 hp to the wheels on stock 100% untouched heads…so who needs’em LOL.
