340 with edelbrock heads overheating

Whatever. You don’t think it’s POSSIBLE something else was changed?? Or something wasn’t changed to accommodate they new heads?

It damn sure ain’t the new heads causing it to overheat. That’s insane.

I agree, the heads are running cooler than the block. I think i found the problem. Funny thing is i did this same swap 12 years ago and used 273 rockers. had zero problems. no longer have the car so edelbrock changed something or i got lucky last time
