Cheap 318 performance mods.

well, the original poster did mention getting 302 heads for it in the original post. if he is thinking upgrading heads, the best bang for the buck will be a set of OEM magnums, because you also get the added bonus of 7% more lift on the same cam due to the different rocker ratio.

looks like he already bought the '77 318, so that is water under the bridge. personally I would have sought out an '85-up 318 or a magnum 318 as my base to build because of the OEM roller cam hardware, and in my experience, regrinding the factory roller to something a bit more aggressive was less expensive and more reliable than a flat tappet cam cam and lifter package.

Personally and in my experience I cant see seeking out 318 parts (302 heads) the natural progression that I went through as a young man is play around with the 318, cam, headers carb exhaust, ran good but want better ... seek out and find a 340-360 ...that is the natural way of things not seeking out heads (done it) paying to have them redone at a machine shop (done it) machining this porting that only to end up with another engine (340-360-5.9 Magnum) any way and that one that you dumped all the money into to start with sits in the corner collecting dust (done that too unloaded it at a loss... ) I understand having fun and hobbies cost money but what any 318 guy is truly after is only satisfied with a 340-360...it simply costs too much to get it out of aa 318 that Vizard build will be the proof of the exuberant cost . OP said cheap I think that has been covered here there is only so much "cheap upgrades" on a 318 then you hit the "now its getting expensive what do you want to do build the bigger engine or try and prove something with this 318...?" wall...
