Just got my old LA 340 X heads back from a local retired engine builder.
I left the heads with him for some economy street performance porting as this is not a track engine. I had to remove the heads to swap out some bogus hyd roller lifters so I thought what the hell I'll have them cleaned up. These heads were prior used on a NHRA stock Eliminator LA 340 and had been acid ported. I also provided a new in the box Edelbrock AirGap intake that he touched up. The flow numbers shown below are through the intake and the head.
I would have liked to seen a little better exhaust numbers, but for $200 I'm not going to *****.
The Gent that did the work told me, which I agree, that its not so much the numbers but the shape of the port that really makes them work. Maybe when I get my back in better shape I'll post some pic's of the heads.
