I have a vortec 350, I put a comp 08-801-8 cam, valve springs, 1.6 roller rockers and headers on it, when I got it tuned it would lean out after 5000 rpms, injectors wouldn't push enough fuel, I got a set of heads with 185cc intake runners, 2.02 and 1.60 valves and longtubes, what can I do to get enough fuel to still run it up to 6000 rpms, I've looked into marine intake but can't find any for sale.
