Dart's new Platinum Series PRO 1 aluminum cylinder heads for
small-block and big-block Chevy V-8s are the direct descendents of
Dart's Pro Stock engine program, incorporating sophisticated wet-flow
technology and improved combustion efficiency. Affordable Platinum
Series PRO 1 heads offer exceptional performance in street/strip,
bracket racing, marine and high-performance applications.
"Essentially we've reinvented the standard small-block and big-block
cylinder heads," said Dart founder and president Richard Maskin. "There
were enough things to change that it justified making brand-new heads
from scratch. Our goal was to take advantage of the parts and
technology that are now available and bring these heads into the 21st
Both applications retain the original bolt locations and use stock and aftermarket bolt-on components.
"Even working within these limitations, we made big gains in efficiency
by incorporating all of the data we've collected on the wet-flow bench,
the dyno and the race track to improve the total package," Maskin
noted. "When we were finished, the sum of all the improvements was
The new PRO 1 heads' intake seats have five distinct angles – a direct
result of Dart's wet-flow testing. Each of the five angles provides a
shear point for the fuel to go into suspension before it enters the
chamber. The valves are back-cut to condition the fuel before it enters
the chamber. As a result, the engine pulls more fuel and makes more
The spark plugs in Platinum Series PRO 1 heads are located as close to
the top and center of the combustion chambers as possible, shortening
the distance that the flame front must travel and producing a more
uniform pressure rise in the cylinder.
