In addition to the above recommendations;
Just make sure to remove the chain tensioner or you wont be getting those cam gears out (I think I followed JWT the first time I did mine and it was missing this part if the instructions as my car as a 98 and it took me an extra hour to figure it out the first time I installed my set of cams).
Now, shouldn't take me more thank 45mins to 1 hour
P.S. quick question; does the 98 onwards engines before the RR have an updated/different chain tensioner??
