Porting Vortec heads is like touching up a Picasso...

Porting them well will take them to about 190cc's and 250-260cfm with a 1.94" valve. And if you have a 350 that is approaching 6,000 RPM (very common for most hot street builds) that can equate to some major power.
The vortec heads were a design improvement but they were also truck heads that were produced as cost effectively as possible. Which leaves a LOT of room for improvement on a hot street build. |

AP-I don't think on production Vortec heads you go as big as 190cc's.

you can, its not that tricky, just takes a little more time with a carbide bit. I've done several sets in the 190-194cc range. I keep it there as I usually use a 1.94" valve.

I finished porting the second head last night. I've got to cut the guides down, clean it, lap the valves in, clean it again and put it together. Plan on being ready to put em on and do my clearance checks, pushrod length etc... on Tuesday. Then its time to get the lil "Iron Duke" and 5-speed out and start getting everything ready for the swap. I have made my decision on the trans bolt access idea. Instead of cutting holes to get to the top bolts, thats what I did on my last S10 build, i'm gonna cut a section out of the floor pan, mig four small strips of 16ga. to the underside, lay a small bead of silicone on the strips and lay the piece I cut out right back in place after I get the motor and trans in. This way, if I ever have to pull the trans I can just pull the carpet, sound and heat dampner, floor plate up and have super easy access to the trans bolts
. I've still got lots of playing to do but im gettin excited about seein what this lil flat top motor runs like.
