Arrow Chev 350
The ARROW Series Small Block Chevy Aluminium Cylinder Heads are outperforming some of the best brands in the industry with clean but powerful strip cylinder heads. They are equipped with ultra-smooth A356-T6 aluminium casings to increase CNC flow numbers: upwards of 250cfm on the 183cc and over 280cfm on the 200cc. The alloyed manganese bronze valve guide is a 5-angle competition job, while being sealed with the extremely durable VITON fluroelastomer make it the cylinder head to have. Our recommended gaskets come from the increasingly popular FELPRO range, named 2016 Performance Engine Builder of the Year.
