Has anyone tried the new Edelbrock heads with stock or slightly higher compression pistons? They advertise that the heads will increase compression ratio to 9.5:1 which would work not too bad for my LPG application and the cost of cast pistons verses having to go with forged pistons to get higher compression may be worth the benefits that the aluminum heads with give me. What benefits would I get going this route vs. high compression forged pistons and the stock heads?
Any ideas or thoughts out there on this one?

I love sticking my head out the power sunroof. It seemed to run well but I know LPG engines take a hit in power unless they are built strictly for using LPG. The previous owner never did anything to the engine that I can see execpt add the propane convertion. Since it had about 255 Thousand Kilometers on the engine I decided it was a time to have it rebuilt properly for propane use (stainless valves, hardened seals, higher compression, HEI ignition, magnaflow exhaust, K&N filter system, etc). I am taking digital pictures along the way and will give a report as I go. So far I have taken a heck of alot of things apart and put very little back together, but I am having a great time doing it and am getting a huge tool collection in the process!
