Head packages require your heads to be sent to T-Man Performance for work to be completed. T-Man heads are specifically designed for your performance needs with proven results. T-Man offers several head configurations from the Street Performer to our Signature Thumper Series. There are optional upgrades available for most heads. They are noted on each cylinder head order form.
