the castings were designed for a longer valve. the machining to make them fit standard length valves is where the problems start to happen. Pretty much anyone assembling these heads does that before they ever make it onto an engine. Whoever you got it from should have known better. The raw casting has much more potential than the machined version.

care to share any other tips with these heads before i reassemble them? i guy i bought the engine from didn't come across as the brightest crayon in the box but the guy who assembled this engine was a total muppet. i'm learning as i go but i'm more familia with Indy heads, not these strangely engineered items.

I had a set before my B1's. They were done by Don Studley. Precision Cylinder Head in So. Cal. (R.I.P. DON) Don was an awesome cylinder head guy, especially Mopars. When I took him my set of Stage 6's he just laughed and said " What do you want me to do with this sh!t"?? I asked him to do his best.. Well, Don did.. Cussing all the way through them.. He put longer valves in them so the spring pockets weren't so deep . He also cut drain backs in all of them to fight your same problem. Don got 360 cfm out of these on his stingy bench. My ET's were in line with the possible HP with these heads. 9.20's @ 144 in Phoenix at 3000# and a glide. As one poster said. These heads can be made to work well in the right hands. He also cut the rocker stands down to use Max Wedge style aluminum blocks to get the best geometry.. These were Max Wedge ports.. 502" low deck. Wish I still had them and Don was still here too. Chris..

I just ground notches into the pockets so the oil drains out. I have never had any issues. These heads seem to be working ok for me. I am happy with the performance.

don't try to run harland/sharp rockers on them. No standard valve cover will fit over them.

Don't mean to hijack, but anyone have any chamber pics for their stage 6 heads?
Thanks, Jeff
Mine look like this. They will definitely receive some attention before seeing service.

Yep. Had to use fabricated covers with mine to. Standard stamped or cast ones wont fit.

these are mine now they've been cleaned ready for reassembly, looking at the valve guide pedistal, i now realise how much mine have been ported.

This is a lot what mine look like other then the square notch around the spark plug, Any idea why that is in there? Mine is smooth blended into the chamber. Mine have been cut down to 73cc chambers.
