Aluminum Intake corrosion

When I bought my edelbrock heads about ten years ago I did a home port job on them and found a casting flaw in the pushrod pinch area. I put a bit of JB weld in it to seal the slicht hole and low spot area in the intake port. Has been on my 410 for the last ten years and now that I have put trick flow heads on my 410 I have put them on my 318 and have never had an issue. So tell greg con to stop[ blowing out his arse!
