Edelbrock head problems
By Matt - 08/14/2000 11:56:27 AM; IP 194.197.68.45
If you go with Edel Heads, these are the problems I ran into:
1)If you reuse the factory rockershaft bolts, 2 of them will have to be trimmed 1/4" because two of the holes are not tapped far enough. I did this and when I tried to torque them to the proper ft/lbs, they kept turning and wouldn't tighten...I think they started to pull the coil threads out...I'm really upset about this.
2) Factory GT 390 exhaust manifold do NOT match the bolt pattern on the heads...I'm really really mad about this.
3)The heads of the factory head bolts are too large to fit into the recesses on the heads. The only way to correctrly do the job is to get a new set of head bolts that have a smaller head. Edelbrock gets a big thumbs down for all three of these issues.
This thread, so far...
