Re: Are these heads worth swapping
on what kind of car??
sure as hell won't work on a 305TPI
on an LS1 you would see maybe 15hp with the stock ls6 heads, and maybe a bit more with the patriot heads...depending on how much they were ported

Re: Are these heads worth swapping
like i said, on stock cam the heads will give minimal gains...just not enough demand for flow.
1.8 rockers would help out, those alone should be worth 10-15hp or so.
if you were getting the heads REALLY cheap or free...than it may be worth it. but to buy them for a stock cam car...not really. also realize that you'll need new head bolts and gaskets...so it adds to the cost.
with an A4 you are better off spending $$ on something like a converter.
