which peice do you think is off the edelbrock perf rpm intake world products sportsman 2 heads and a stock 350 block the problem started after i put the heads onany body know which to check and what the proper angles should be or how or where to get info it seems like weird problem cold it be i have to use a worlds products intake with the heads or could the block deck be that bad, its a rare weird problem but the oil is being sucked in the intake and baking into tar on the back of the intake valves could crankcase pressure be to high and busting through or would that just go out the valve cover
