30 hp just doing a valve job? Or did you mean a port job? I am building a 355 with a lunati Voodoo 262 cam, vortec heads and stock aluminum Volvo Vortec intake. I have bumped the compression to 9.35:1 and am expecting to see 350ish horsepower. Remember to be nice to the alpha because it cant take much more than 350 horsepower.
