Just got the 915 heads on my 451, and checked the cranking compression. Getting 210 to 215 PSI on all cylinders. Also installed some Jegs Ceramic coated headers, and they fit nicely. These look just like the Patriots, but a little better price. Maybe Patriot makes them for Jegs? I am thinking they do. Only had to raise the motor 2-3 inches on each side enough to get them in there. They are well built and nicely finished.
