Well to get the compression up you can use the Mag heads as kraby suggested. There are lots of choice for pistons too. A combination of the two will probably yield the best results. Aim for 9.5:1 maybe 10:1 compression. Top it off with a eddy air gap intake and a cam to take advantage of the better flow and you should have a fairly stout 360. The comp cams xe268 would be a good place to start. Probably get away with more cam but it would make it a real stump puller.

There are many guys on here more knowledgable than myself that can come up with a better combo but that gives you an idea anyways.

FWIW, the 360 I built last year for my Barracuda is using magnum heads. With KB flat top pistons and the block machined for zero deck it has 10.6:1 compression. I am also using the Comp XE268H cam and with the 1.6 ratio magnum rockers it has a little over .500" of lift. This is about the limit you can go on lift on the magnum head with out machining the guides for more clearance. I also have a Cross Wind intake. This combo pulls hard from 1500 rpm to 6500 rpm and is a blast on the street with it's wide power band.
