318 combo

Thanks for the replies. To answer a few questions, I'm running 2.92 gears, and propane in Australia is around the 100-102 RON mark octane-wise.

The EQ heads do look interesting. I like that you can still use LA-style intakes on them as well. Is there much to be changed valve-train wise? If I do decide to go for the EQ heads do you think it would be worth going for roller-rockers if I have to change the rockers anyway?

I'm wondering, in terms of 'bang for buck' if the changes required for the EQ heads, versus the LA-X heads would be worth it?
