You can purchase your guides, gears, etc at
www.autopartsgiant.com You can save some money from doing this.
The startup rattle that you hear for a sec is the tensioners building oil pressure. I'd replace the tensioners also.
I have an extra timing chain crank gear that is new that I never used - i bought two thinking I would need them both when the new revised type is one piece unit with to rings...You can have it for 10 bucks plus shipping if interested.
Be carefull on the timing.....
