[cody4359]

so i bought an 87 comanche with supposedley 2000 engine/tranny. the exhaust manufold is cracked but it doesnt have the pre-cats that all the 00-01 header options show. can somebody let me know what casting number a 00-01 and pre 99 heads should have. thanks

If the head has bolt holes to bolt up the distributorless rail then its an 00+ head.

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

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.
