Timing chain

This might sound elementary need suggestion and part number for a high Quality timing chain my motor is 429scj street driven should I get a roller chain or regular one don't want to have any clearance problems and have to grind on the block. And to double check me I turned the motor where the chain what tight put a straight edge from sprocket to sprocket and it measured the .433 is that to much slack or not. I was thinking sense I have to motor out and apart I should change it thanks for any advice

Call Lem and get a FMS roller timing set and forget about it!! Oh and get the trick cam retainer plate too!!

Thanks I'll ask him about the trick retainer plate
