## Temu's Cheap Heads
Temu sells low-cost, low-quality GM Vortec cylinder heads for $350 assembled and shipped.
## Distorted Combustion Chambers
The combustion chambers are distorted into a heart shape instead of round, reducing performance.
## Poor Flow Test Results
Only the exhaust side passed a vacuum test; intake valves lacked back cuts and had sharp angles.
## Why This Matters
These heads won't boost engine performance and are unsafe for non-Vortec small-block Chevys.
## Key takeaway

Temu's $350 Vortec-style cylinder heads have distorted combustion chambers and poor flow, making them unsafe for small-block Chevys.
