Will these be all you ever do? Don't want you throwing good money after bad.
If your dealer or favorite independent shop has winter sales, you could probably get Andrews 26G cams, adjustable pushrods and a Baisley spring done for that, but it would be a poor choice if you were going to do heads later... Depending on the shop's winter labor rates, maybe a 95" as well, boring your cylinders and using SE cast flat top pistons, but that'd probably take you a little over. If you had the 95" conversion done, you wouldn't need the adj pushrods, though, as they'd have your heads off...
