318 head porting for the average joe

well when I had my 83 D250 with its 318, I put a set of EQ Magnum heads, a stock 360-2bbl cam and a Performer intake and carb on there along with some Hooker super comp headers and it made a HUGE difference. HUGE. and I never pulled teh short block out of the truck, the bottom end had never been touched, with then 130K miles. this car has 56K original miles. I know that what I plan to do here is not exact same combo as that truck engine, with the EQ and magnum valve train 1.6 ratio//

and this engine I am wanting to put these 302 heads onto, with a slightly different cam (looking at comp 252, EXACT same as stock 360-2 bbl cam except that it has 0.015 more lift... ) will somewhat make up for the difference in rocker ratio (that stock 360 cam's .410 lift became .437" with the 1.6 RR) with another Performer (maybe an Offenhauser, I have both, both are dual plane aluminum will probably make more difference which one is closer and easier to dig out, as the determining factor as to which one gets used) and a choice between a 500, a 600 Performer carb or one of a couple fresh ready to run TQ's that I have, plus a lean burn swap out, that I might wake this thing up at least "some".

Note; I was looking at that 252 cam (I have a 260 here, wouldnt have to buy that) because EVERY spec is IDENTICAL in every way to the cam I put in that truck. EXCEPT the lift on the 252 is 0.015" more than the 360-2bbl cam. splits the difference between the 360 cam with stock rockers and the 360 cam with the Magnum's 1.6.
I know that this Fury only has a 2.76 in it, Id like to go to like a 3.08-3.21ish (eventually) that truck had a 3.55 Dana 60 in it, never did anything with that, same rear end before and after.....
I'm not looking for a race car with the Fury.... even waking up its stock engine, I don't see that car ever touching 4000 RPM. That' s just how we use it. but from idle to that point, it definitely needs some help in motivation department. we don't put but a couple thousand a year on the Fury, with covid and the lack of cruise nights etc it never came out of the garage last year. just looking to perk it up a bit, and I have what I have on hand, at this point. Worth a weekend of thrashing on it or a waste of a good weekend?
