For those that didn't know, Edelbrock came out with a new CNC chamber round port for us to play with. It has a more modern heart shaped chamber that looks pretty nice. The rest of the head is the same, but now you can get a chamber that wasn't designed in the 60's. 61515 and 61525 are the numbers for the complete heads, 72 and 87cc.
These are going on my 474 and back in the car in a couple of weeks, so I'll be able to post updates about the timing needed and performance. I'll run these as "Out of the box" for the rest of the year, then send them off next spring for porting.
Anyone know the best way to get 4 years of dust off a car?
