I believe the Edelbrock 6085 heads are straight plug heads and wanted to know if there would be any problems with plugs interfering with SLP 1 5/8" headers?

That's what I have. Clearance is only close on one plug but there is still more than enough room. The clearance problem is more of a problem when installing the plug rather than when they are installed. I am running 90* MSD heli-core wires and no heat/header related problems.

Yes, they will fit, but like James mentioned getting the plugs in and out can be interesting. Be prepared to "customize" your spark plug socket. I had to find one that had a hex pattern on one end so that you can get a wrench on it, and then cut the length of it down by about half. This is the only way to get it on the spark plug since the headers are so close. But other than that it's not hard.

No interference when they're in, the hard part is changing them. Plugs 5 and 6 are the hard ones, for 6 I had to unbolt the headers and lower the spark plug down on a piece of dental floss then pull the dental floss (which was wrapped around the plug) to spin it into the head. I have 1 3/4 ones though so maybe there's less room, plus the AIR tubes are a total pain, if you don't have those it's a lot easier. The rest of the plugs are extremely easy to change though.
