Some more progress. The intake ports have heavy casting marks. Would it be beneficial to weld up the smog holes and the cross over port in the exhaust?
I'm all done other than port matching the intake ports on the heads. I was able to just clean up the ports and bowls and not get too carried away. The majority of the casting marks are gone and what's left is blended. I was able to do this quickly and easily because I had the right tools. I used to build 1911's so I pulled out the old Foredom and dremel tips. I made a long bit with brake line. The dremel tips fit snugly into the line and chucks right up into the Foredom. You can hold the brake line in your fingers (like a pencil) and control the grinding tip. Your other hand is hoding the tool. If you do this you may need a glove. I am able to control the RPM's with a foot pedal which is almost a must for me. An old trick to get a stipple type finish to to bend the brake line a hair and then use the metal ball. I spins out of balance and gives the surface a rough type texture. I did this in the intake ports so the fuel can kind of atomize better. After I was finished, I pressure washed the heads and stuck them in the dishwasher. Good thing the wife wasn't home

I wouldn't worry about it too much bud. You've done a nice job cleaning them all up...I'd leave it at that and call it good =D. I mean hell, my exhaust ports still have a crossover passage lol, and they flow over 250cfm!

I've been working on the new stroker. I have port matched the manifold to the intake ports as well. The port size on the holley manifold was pretty small. I was surprised that it didn't take me long at all. I am going to fine tune the port size when I get the heads bolted onto the block for the last time. I did put the heads on the block and check it out without torquing anything.
