I'm looking At A Tunnel Ram For My Iroc. The Ram Has No Center Ports To Match Those On My Heads. It Says It's For A Small Block Chevy Tho. Whats The Deal? How Does It Work Without Using The Center Ports On The Heads? Sick

 

There is no center intake port on small block Chevy heads. The center passage is for exhaust gas circulation to heat up the intake manifold for better cold weather operation. You do not need this passage on performance engines, as you do not want any extra heat in the intake.

 

Thanks Pete. Sick
