heads

[WILMASBOYL78]

The 290 heads are a good choice for a street performance BB build....chambers are little more open than the real early closed chamber heads and they have the oval ports, much better for low-mid range torque.....upgrade to 2.19/1.88 valves, unshroud the chambers a little for the larger valves, some minor port cleanup, good hardware and you have a great set of BB heads that will easily support 500hp. My next build is in progress with a set of these heads....another tip: if you are using a 2 bolt block add the releifs in the top of the cylinders like the 4 bolts had..helps those larger valves to breath.
