I like the sound of this thread.

I would like to know how to install bigger valves also.

You can gain some flow by just opening up the seats/ports you have out to where the valve seats. Then grind the OD of the valves you have down to where they seat(magic marker, lap in, cordless drill and pedestal grinder) Good eyes help also.(something I've lost with age)

If your really brave and keened eyed, you can change the angle under the valve head to remove material up to the seating ring. Drill press and a small file. Blend back into the radius.

Remember, it's not about bigger valves. It's about bigger seat ID and the smallest valve OD that will seal. Stuff that has to run around the corner can't get there as easy.

Which is why I asked for a poboy way to do the seats

One of my first mod clones I opened up both valve seats .050. 27mm intake valve & 23.5mm exhaust valve. Works great, don't have a Dyno or flow bench but the 206s don't like getting passed. That's good enough for me. Still running the motor, try to run it around 8500 rpm.

nice thread... I've done so much with so little for so long... I'm pretty much qualified to do anything with nothing
