15 to 20 more horsepower with “Undercover Ported” Open Chamber heads

We have been working with the Chevy “Open Chamber” heads for years. If your rules require the use of “open chamber” heads, the ‘441, ‘487 & ‘993 heads work the best. While these heads are not available new from Chevrolet, we have a good supply. We can also modify your open chamber heads.

Our “Undercover Porting” will improve the air flow of stock open chamber heads from 203 cfm intake and 142 cfm exhaust to 225 / 230 cfm intake and 160 cfm exhaust. This air flow improvement will result in a 15 to 25 horsepower improvement while maintaining a stock looking ports!
