Sir Sam Posted August 3, 2011 Share Posted August 3, 2011 If the head has bolt holes to bolt up the distributorless rail then its an 00+ head. Link to comment Share on other sites More sharing options...
cody4359 Posted August 3, 2011 Author Share Posted August 3, 2011 well i found the #0331. my next question is ive read a little on getting a -99 header to fit on the oo+ head and have kinda been getting a mixed message. i have found a new banks header on CL, along with a gibson, and APN shipped for pretty cheap. i don't want to get a part that is more and destroy it just to find out it won't mork. i read that some clearancing will be nessary but i forgot to save that page and can't seem to find it. doesn anybody have more detail or can point me to a link that does, thanks Link to comment Share on other sites More sharing options...
75sv1 Posted August 5, 2011 Share Posted August 5, 2011 Should fit. I wrote a long reply, but wasn't logged in. The bolt holes should be the same. The later heads have smaller exhuast ports. Also, some had pre cast. So, the headers might no be listed for late models, but should fit. Tom Link to comment Share on other sites More sharing options...
