SBC we are currently working on. Compete build (previous post shows port and polish of the heads). More details as we progress with the build.

It's been a minute since we last posted but we are still here grinding away.

These were originally194 Heads, we put 202,16 valves in it and opened up the bowls, trimmed the guide boss and did a full port and polish. We are not quite done yet, as we will still do a flow test next week and will post some numbers.

Our customer wanted to keep the ordinal double hump heads but maximize the engine performance so he went with the bigger valves and the port ad polish.
