I am working through head options for my Wife's 360.

It's a 1976 360, factory 2bbl truck with an upfitted 4bbl factory intake. I will be going through it to upgrade the cam and am looking into the heads.

First off, I have the 915 J-heads off of my 318 that are just weighing down my shed. Will the milled 56cc J-heads work on this engine? If so, what sort of compression ratio could I expect?

If those won't work, are there budget-oriented upgrades that I should be considering? Magnum, aftermarket iron heads, other castings? This is a low budget truck that will get very driven very little, and not very hard.

Thanks!
