I will be swapping out my performer intake this winter for a Systemax. I have a set of fabricated valve covers I would also like to run but cant without a 3/8" spacer. Now I have seen this done many times but in every case a aftermarket cowl type hood was used, but have a stocker. I have no intentions on swapping the hood out just to run a set of valve covers! So has anyone seen this done, or did it themselves? I did have a 3/8" spacer on my edelbrock at one point and it did hit one of the ribs on the hood, that is until I flattend it out! Just kinda tying to get a plan before I take it apart and have the AN fittings welded in the fabbed covers and if it wont work just weld them in a set of stockers.
