The Bravo 335 bbc rectangular port heads are perfect for 454, 496, 540 and 572 street/strip engines. These are what we now use on our 505, 555 and 572 bbc engines. They produced up to 822 hp with our Comp solid roller cam in a 572 mild drag setup and single plane intake manifold. None of the low cost bbc heads on the market have this performance that we know of. Fully built, ready to install.
These heads are not suitable on 396 or 402 engines that have the less then 4.250" bore size. With the larger 2.250" intake valve on the BRAVO heads, it can interfere with the cylinder wall. These heads are well suited on 4.280" and larger bore BBC engines. The recommended compression would be from 9.8:1 to 10.5:1 with pump gas, taking advantage of the aluminum castings.
We also have these heads set up for use with hyd. roller and hyd. flat tappet cams. See our other listings for # BRAVO-274 for the hyd. roller cams, and Bravo-272 for the hyd. flat tappet cams.
