LD340 for W2 heads - Have you seen any?
There are. These are long valves and I have the installed height at 1.900. It took a lot of shims to get there!! I have run this combo on my 422 and it will put the car sideways if you floor it at 30mph. Previously ran the heads on a 360 and it was going 11.40s but really didn't start to make good power until 5500 rpm. I thought these may be a good match for more cubes. The 11.40 was with the indy rectangle port intake and these heads.
