He keeps unbolting parts from his car so I had to get the grinder out again.

Have you ever tried putting them on a flow bench and putting some putty in the floors of the intake runners to see if your air speed increases? When Ralph took his intake to my neighbor to have it flowed for his 63 they put putty in the floors to raise the intake runners and it picked up an immense mount of airspeed. But Ralph didn’t have the time to do all the intake runner so he bolted it back on.. this was a huge find and pick up of airspeed and flow. This is a Lamar Walden Z 11 intake. He just put this on his car again last fall and went the fastest and the quickest he’s ever went. And has a lot of room for improvement. However what you’ve done with the parts you have is incredible, 690 heads running the ET and mile an hour is incredible. Just a suggestion that you might try to build up the floors a little bit and see what they heads flow. I know will do just about anything to go faster!:juggle:appl F52755B0-4B28-4554-8B51-D6AB28E79DD7.jpeg

Which heads and what kind of flow numbers? Just curious.
Just the iron 690s I've been running. Last time they were flowed was 323 cfm @ .700. I just did a little more refining and laid back the ridge areound the intake valve in the "chamber". Also wanted to do a heavy burr finish to help keep fuel in suspension. I doubt the flow would be picked up much with these minor revisions.

I bet it will improve flow. I'll be right over to making silicone casts of the runners so I can take measurements! :brow

I would try it. Not sure if I’ll be flowing them again or not.

I have more swatting to do. Had a couple ports flowed by a very sharp person where I trust the results as very accurate. Lost a few cfm but the last time they were flowed the results may have been less than accurate. This time I trust the results 100%. I need to find the choke point on the exhaust so a little more grinding is needed.
