Dose it work with vortec heads?

 

Also how much would it cost to get the stock tpi ported

 

Email ken, he has made the vortec base and might have them in stock.

There is a guy on eBay porting the stock base for $200 not worth it IMO the base is a restriction but so are the runners. You should look into high flow. Slp, accel, edelbrock or better yet tpis Arizona speed and marine.

You might want to look for a vortec base hsr.
You might be able to get the natural version not sure the pn I think it’s a 7542.
