Frankys Cheap 419 - 1969 Ford 351 Windsor

While working on this project, Dale had an interesting offer. During the time it took to collect the block, all the parts, and get lined up with our machine shop, Dale had worked a deal to offer his own high-performance aluminum cylinder heads to the market. So, for the first time, you're going to get a look at the new Prime One 210F cylinder head (PN 575-21210). Like the Prime One line of stroker kits, this cylinder head offers the end user an incredible source for increased performance at a tremendous value. These aluminum small-block Ford cylinder heads have 210cc intake-runner volume, 75cc exhaust-runner volume, and a 60cc combustion-chamber volume. The 210F is designed for 2.02-inch intake and 1.60-inch exhaust valves, but you can stick 2.08-inch intake and 1.625-inch exhaust valves in them. They are machined for a half-inch head stud, and they come with hardened valve seats. The exhaust port is raised 0.250-inch, and they offer a 51/48-inch-thick deck surface.

Dale reported out-of-the-box flow numbers of 256 cfm at 0.700-inch lift on the intake and 180 cfm at 0.700-inch lift on the exhaust. As you can see in our accompanying flow-bench chart (courtesy of Carl McQuillen's Racing Engines), we got almost the exact numbers on the intake, but the exhaust was a little lower than reported. Of course, that could be because of the variance in flow benches. The bottom line is, at only $695 a pair (bare), the 210F offers an incredible value. Pro Power plans to offer this head-complete with components for a hydraulic-roller cam-for only $925 a pair. They were the perfect heads for Cheap Franky's project small-block.
