Don't the angled plugs get really close to the heat? You don't. I kept frying the #7 plug boot. It was my own stupid fault for buying Edelbrock heads. I knew there was better heads on the market with straight plugs. In the end this was my solution: Shorty headers as I didn't want the headache of long tubes. Decided to have them made out of stainless while I was at it. 1987 Fifth Avenue - 512/518/D60

Don't the angled plugs get really close to the heat? I used the Mopar 452 heads (straight plug version of the Edelbrocks). There is a lot more clearance with the straight plug heads. Previously I had run the angle plug heads and had problems burning up one or two of the spark plug leads so I switched heads. What you really want from a clearance standpoint is an angle plug head on the driver side and a straight plug head on the pass side. That would work the best for the spark plug wires.

Maybe I'll snag one 452 head for the passenger side.

Equal length highly over-rated for a engine with limited RPM and "warm" cam with moderate OL and wide LSA. More trouble, more $$$, less efficient than shorties (but better than manifolds and very tight for clearance): fabrication from "weld ells". Boffin Emeritus

Is the EB website wrong, and are the 84cc heads actually straight? Angle plugs don’t work with c-body hp’s and I need to go with straight plugs.

And there is a foot note in the catalog saying so. The 75cc version are still angled plugs. 68 Satellite, 383 with stock 906’s, 3550lbs, 11.18@123 Dealer for Comp Cams/Indy Heads

Too bad EB doesn't have that note on their e-street page - kind of important, and was going to cost them a sale. I've been banking on using the Source Stealth heads on my stock-appearing build because they were about the only straight-plug option. The USA-made E-streets also flow a little better OOTB, too.
