Duster 340 you forgot BFH and Prybar LOL! Good instruction. Leave everything on header loose until you have all the bolts in place on head. Right side 30 min left side 4 hours LOL!
well i havent tried hedmans but yeah sometimes prybar and BFH is very usefull:) very good advice also to leave bolts loose until they are all in there second bolt from the front on driver side are usualy a big pain and the two last bolts can also need some creative thinking with most headers unless your hands are the size of a 2year old ;)
also i forgot to say that you may have to lover the engine down with headers just put in place but not bolted to head, it is a thight fit everywhere..
i have TTIs on my car now and they are alitle easier to fit but much harder to make them fit the wallet,and i need new ones for my new motor :(
