"Looks like"... It leads back to like Rusty rat rod was saying everything needs to be checked. We look at these pictures on the internet and try and diagnose from that when it's op who needs to do the leg work. I always make sure I can slip piece of rounded welding wire behind the spring and a lifter to check clearance so it's not hitting the edge of the spring...
My Hughes rocker are not even close..
All of my 273's needed clearance...
Side to side clearance is simple shims that Hughes I thought gave me with my rockers....
Going to put this out there so I can be done with this...
Check everything! If you need some side to side shims and center them do so. If you have a very small sweep that's right in the center of your valve with your tip, if you can get a piece of .030 welding wire to slip behind the valve underneath the rocker, you have two threads or less showing on the adjuster and your push rods not hitting anything you are probably good to go for 500 ish lift street car... In my opinion...
If you're going to the wall and making sure everything is perfect ultimate perfect for ultimate durability and ultimate drag racing and all the gurus got in your head that you're going to gain all this horsepower I would definitely call B3 I'm sure it's a couple hundred dollars for his kit the man can't be doing this for free, do whatever he says and likely have to get custom length push rods once it's all jacked up in the air and likely have to redrill your head for push rod clearance... And not that that's any kind of big deal or big expense for someone who's going that far with their engine...
And one more thing all of this starts to get really old., Week after week month after month year after year of going over the same small block Mopar. The carbs the spark plugs the oil the valve train geometry the stroker than not the stroker that head flow.... good Lord BORING!!!...
