I am about to start building my 91 z24 5speed. I am considering using the full top end kit and haveing them do my custom tuning an build my headers. Has anybody here used them for parts or services? If so let me know how your experience with worked out.

i wouldn't touch em.
i've never heard anything good about them. besidees i'd be willing to bet that a set of 2000+ 3400 heads upper/ lower manifold would flow more than even their most radical port job. furthermore, the stock 3400 exhaust manifolds flow more than the stock, and if you want headers i think six shooter on www.v6z24.com is still looking to make his custom headers.


watch for flying sparks!!!
