Cylinder Head Exhaust Flow

jrstock · 03-13-2015, 08:28 PM

I've recently come across a set of new set of cylinder heads. These heads flow the same on the intake as my old set but significantly more on the exhaust.

I've dyno'ed the new heads and seen a significant hp drop.

Any ideas on what modifications are required to make cylinder heads with better exhaust flow work?

Anyone have experience with this problem? What changes should I be looking at? Cam? Headers? Something else?

The combo is sbc with 520 cylinder heads.

Thanks in advance for your advice.
