Re: 418W build up - RPM or Vic Jr.
Just make sure whoever does the head work does a good job and has a good reputation.
I just flowed a head for a customer, different brand but he insisted the person who ported his heads has been doing it for 20+ years and is one of the best! He claimed 300/240 cfm out of it, and when I flowed it, using the exact same bore size, depression, and even a pipe on the exhaust, it went 281/195 intake/exhaust. Now he know's why his car only ran 10.40's and not 10.00's!
I let him watch so there was no chance of me fudging...so be careful.
And it sounds like a good build. It's very common that even after you do a combination "right" you will still make changes over time to it. That's kinda the fun too.
