how much does it cost to do some portflow work on a b16a2 head .. i see people selling them for a lot of money. so the labor must be high

 

For just the headwork alone it'll probably run you right around $900 plus shipping... With new spring, retainers, valves, guides, etc. it'll easily cost you $1500... If you want so see what Scott's Portflow head added up to check out the link to his motor in my sig... Kind of will give you an idea... Just about every built motor we've ever done runs them and Tom does awesome work... Hope this helps...
