Tea vs TSP Vs Waldens' Machine work for the 5.3
Actually we did answer the question correctly. Exactly what part didn't you understand. I suggest you lookup the word "sideline" in a dictionary first. TSP is a well known and respected shop which will sell you almost any speed part you can name and install it also. Their work is first rate and they stand behind it. However, heads are a sideline for them, not their primary business. You claim 445 hp na for your car on a Mustang dyno. Considering your mods list of a small cam, basic ported heads, and bolt ons I would believe that amount on nitrous but not na. Would you please post your dyno sheets and prove me wrong?

They do incredible work and put in countless hours into their head design. They may cost a little more but you will feel and see the HP gain over the other heads.
