Chevy 180cc Vortec Bow-Tie Small Block Cast Iron Cylinder Heads
Updated on Thursday, 4/11/24. We have reached an agreement with a company in South Dakota on the sale of our Vortec, Vortec Bow Tie and Dart SS cylinder head programs, machinery and processes. More details to come soon. They should be up and running and supplying heads as soon as May 1, 2024.
Talk about awesome torque and horsepower all in one cylinder head. The 180cc Vortec Bow-Tie is the best “under 200cc intake runner head” on the market. It is excellent for circle track, street, drag racing & marine applications. Technical Note: Chevy calls this a 185 cc intake runner cylinder heads. Actually, it is 180 cc’s in stock form. Chevy also discontinued the 220 cc intake runner Vortec Bow-Tie castings.
With our CNC Sportsman Porting or “Undercover Porting“, the 180cc head will support engines making over 540 horsepower with incredible throttle response. This is one of our favorite cylinder heads because it just works well.
Vortec Bow-Tie head
The Vortec Bow-Tie head has a superior chamber design.
The Vortec Bow-Tie heads are beefed-up Vortec passenger car heads with better air flow, a thicker deck, both center-bolt and outside valve cover bolt patterns and the Vortec and conventional intake manifold bolt patterns.
A stock Vortec Bow-Tie head will flow 234 cfm intake and 151 on the exhaust. With our “Undercover Porting“, the intake flow improves to 256 cfm and the exhaust will reach 184 cfm.
Our CNC Sportman Ported Vortec Bow-Tie will flow around 200 cfm on the exhaust and 265 to 275 on the intake with an intake ports volume of 195 cc’s.
Racers love the Vortec Bow-Tie head because it produces such a flat torque curve. Meaning, it will usually produce the same torque at 6,300 as it did at 4,000 rpm. Translation: Instant throttle response whenever you need it.
We can supply bare to complete Vortec Bow-Tie heads and rework your heads.
Aluminum Intake Manifolds for the Vortec Bow-Tie Heads: The Edelbrock 2814 intake will fit the Vortec Bow-Tie heads. Depending on track rules and requirements, other intakes like the Edelbrock 7116 or 2925 Super Victor will also fit. In each case, it is critical that the intake manifold properly fits the heads.
