Hot Rods 327 Chevy headers question

Hi guys. Does anyone know whether the exhaust pattern changed in the 327 over the years?
Thing is, I want to get rid of my old cast iron headers and buy some sexy headers. Saw some on eBay but they were listed for 88-97.
Does anyone know whether there is a difference?
Thanks gents
Peter

 

Mine is a '67. should mention that.

 

The year difference is most likely due to the vehicle design changes. I don't think the heads changed.

 

For what its worth, I've had a few different headers on my 327 before I finally settled on the ram horns from Speedway Motors. I don't believe there was any change and never had an issue from header to header from stock exhaust

 

The newer small blocks that were from the early 90s up that were LT 1 had a D shaped exhaust port and required a specific manifold or header... The old style will bolt on but blocks about 20% of the exhaust port...

 

The LT-1 heads were "D" or inversion port and require matching headers. Some angle plug heads require different headers. The bolt pattern is the same for all years.

 

Thanks guys. Just what I wanted to hear. Made my day. In fact, the HAMB always makes my day. Cheers!
