I'm looking for 4-1 (racing) 1pcs header for my D16A9 engine and I can not find it. There are other for D series, but the problem is that I have one (4-2-1) and I comes 1" too low, 1" under the oil pan. I think it is because it is not specifically for my engine.
Which car models/year have D16A1 or DOHC ZC engine?
Can anyone help me? What and where to buy.

Setup:
-D16A9 non VTEC, DOHC, stock 130HP engine
-Ported and polished head
-Crespo stage 5 drag&track racing only camshafts
-40mm ITBs
-11-12:1 CR with ENDYN rollerwave pistons
-60mm exhaust
-? header

 

I have a big tube 4-1 for the D16A6, you may need to do a little port matching for the D16A1 head. The header needs to be coated since it was on a car through the winter months with only hi temp black paint.
