mazda/kia b5 camshaft trouble

Hi Guys, seems I found the right group of mazda fanatics to help me out on my new venture.I do oval racing and use to run datsun pushrod engines, oure sanction body opened methanol fuel injection in oure class to move up from the old sidedraft carbs but, you can only use engines that came with fuel injection, I opted for the kia b5 super efi engine as it came out with wasted spark, no dizzy and injection, it seems a perfect motor for accelaration hence short stroke big bore, lightweight parts and crossflow head, we are limitted to 1660cc so I bored out to reach 1648, high compression 14 to 1 for methanol fuel, this engine is basically the mazda b5, I need to run a high lift 300 degree camshaft, problem is the adjustable rockers I sourced from a mazda b6 jams against the side of the camshaft as it seems the rocker arms are to short to run center on the camshaft, could anyone help me with advice on how to solve this problem, and does anyone know of racing valvetrain parts with correct rockerarm ratios for my application, thanks for sharing and helping fellow mazda FANATICS!
