Hi Rody,

I am going to purchase a brand new VSR-04 from the surplus of a fellow hobbyist. I am going to run it in a tight track using 25% runner time fuel. I would like to pick your brains about:
1: Do I need to add head shims?
2: manifold/tuned pipe choice? Here in Hong Kong I can't get your tuned pipe set from shops which I am sure is perfect match to your engine. We have OS and Nova here. Because the track is not big, I am looking for acceleration than top end performance.

Thanks you
