A couple of weeks ago I ordered a Pacesetter header from Summit and it came today. The header has round holes for the older style head despite coming with documentation for a 1990-1995 and coming with a gasket with pear shaped holes in them. There is a hole right where the top of the pair is (bolt hole? in the header). Would it cause a noticeable change in performance if I simlpy welded over this hole?

I emailed summit about the issue and they emailed me (an obviusly standard message) about sending back the item prepaid. Great, first I pay lots of money to have it shipped here, pay customs, and have to ship it back. Not only that, but I have to wait for more parts to come in so my downtime is longer. Not really a good solution. Fixing the damn thing would be better for me.

I was thinking about just blocking the whole and perhaps grinding out a bit of the metal to make the whole slightly better shaped. Would this work and be a good solution?

 

I know it sucks, but if it was me I would send them back for the right ones.

 

Wonder if you need the block-off plates like I have on my '85:



There are two small holes below each end of the plate.

 

Roger,

that's exactly what I need now that I go look at it. However, now that I look even closer, there was a copper pipe that went across and took the place of the block of plates.

Thanks all. I was pretty frusterated and wasn't thinking all that well.

 

You probably have the later style external EGR plumbing that fits over those plates. I have the earlier style that runs the exhaust gas back inside the head.

 

i just got the same header installed today and did you have a really annoying sound coming from the header before you put those bolts in the middle of the one-two pipes and three-four pipes? because my truck is really annoying right now. if that is all i need to do in order to make it good then i will be very glad

 

I've never heard a good word about pacesetter.....you get what you pay for in this case i'd say....thats just my and many other peoples opinons tho...whatever works.

 

will putting bolts in the empty holes help the sound at all?
