400+cuin Clevors for the win.
This. Do they still make the spacers for the intake manifolds?
Pretty sure there are plenty of race builders still doing what is needed to make them work.
Yes, but aftermarket heads have gotten so good that adapting Cleveland heads to Windsor blocks isn't as beneficial as it used to be.
There are some insane Windsor-compatible castings available that weren't around 15 years ago.
The exhaust side of Clevelands was always the choke point, in spite of the giant valves.
The port shape had an abrupt downward bend, and were more restrictive than they should've been for the volume.
The trick modification was to mill off the exhaust ports, and mount an aluminum plate (with re-positioned ports) in its place.
It routed the flow up at a much more efficient angle than did the factory castings.
Jack Roush, Bob Glidden were two guys who had a lot of success with doing that.
A bit later, Doug Yates and Ford re-designed the castings to make them even better.
Yates heads are still worth a big pile of money, even today.
