I have Imco powerflow exhaust manifolds, but still run the stock merc intake manifold. Will aftermarket valve covers such as the IMCO covers fit under the stock intake? I like the idea of using their breather baffle stacks vs the pcv method. Looks like i could mount the breather stacks where ever they would clear, just didn't know if anyone had already been there done that. I currently have the stock covers with the drip bosses ground down due to clearance issues with the gold crane roller rockers.............
