OUR BRAVO 335 FULLY ASSEMBLED BBC HEADS.
FOR USE WITH HYDRAULIC ROLLER CAMS UP TO 620 LIFT. 123cc COMBUSTION CHAMBERS 335cc runners.
This sale is for a set of heads (2 heads)
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 762 hp with our Comp 575 lift hyd. roller cam and single plane intake manifold on a 572 pump gas build. We're estimating approximately 650 hp in a 496 build with the same mid size cam. None of the low cost bbc heads on the market have this performance that we know of. Fully built with premium hardware, 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 setup for use with hyd. flat tappet cams. See our other listings. # BRAVO-272
Solid roller setups also available.
