Sorry, I miss read that. I also thought it was pretty straight forward on the questions.
I’m not sure what a W9 intake cost
My beginning numbers are posted in the Speedmaster head post. I haven’t flowed a stock on lately as there’s no reason to do so.
Base cost to port an Edelbrock or copy is 800.00 base cost plus a small cost for hardened shims and seals. If upgrading to bigger better valves customer pays for valves upfront. Valve job is included in price as is valve guide clearancing if needed. 50.00-80.00 for spark plug clearancing if desired.
Flow numbers with a 2.055 valve (approximately 200.00) are in the 303-305 range.
Ive never flowed a W8 head.
I think that’s everything
There ya go
