Blue Thunder Pent-Roof valve covers

I think the non-comp ones will need clearanced.

The comp versions will probably fit. They also have a couple holes per valve cover for PCV valves, breathers, oil fill, etc.

Just got an email from Dennis, he said my covers shipped out today (pretty fast).

He said I might need to grind a little. I will post an update when the engine gets here.

At least you know ahead of time that there may be an issue , unlike me who spent a saterday installing the dove set up , lashing valves , and when you think your almost done ...

Dennis sent me the tracking info today. All is well...so far.

Just a quick update. The Blue Thunder valve covers from DSC arrived today as promised.
I have not been able to try them on the engine yet.
The quality is impressive.

I started grinding tonight. Oh...on the valve covers I mean.

Got the first one to fit, working on the second one.

Nice! I thought you would have to do that. Pix please when they're "on". I may go to those for a change of pace in the future.

Brent,

Is it the end stands on the Erson's that won't fit or something else?

I have the same Ford Racing covers but have HS roller rockers with Precision end stands. Will they fit under those covers without grinding?

I had the stock Ford aluminum covers from 428's that I had polished and there was no way those would fit the new heads and valve gear. They look nice but don't work with the new stuff.

Comp ones fit on pretty much everything. Factory cast 428 covers will sometimes tag on the end stands - just barely - double gaskets provide enough clearance. Factory tin covers seen to tag on the filler baffles - but clear elsewhere.

I got the extra thick cork gaskets from DSC. They are sweet! I finished up the second valve cover and everything is honky dory.
Pics when I get a chance.
Even though it was extra work, I am very happy with the Blue Thunder valve covers.

Question:
I am going to run the oil overflow tank as per original style. The Edelbrock intake has a casting provision for the hose plate but it is not drilled. Is there a way to add the hole without pulling the intake. I would hate to pull everything apart after Keith did such a nice job.

Here are some pics. Note the organic, unmachined nature of the grinding. This look was very difficult to replicate using the laser cutting machine.
