    what heads will perform well on a 73' 302 block

    A friend of mine has a 302 in a 1973' Ranchero. It has some autozone heads on it now, and a mild crane cam. He wants to run some better performing heads, a performer intake, and a 4 barrel carb. Any suggestions? I told him E7's might be a good upgrade.

    Find out exactly what casting number the existing heads are. If they're a 1970 or so casting, they might be pretty decent already, but its also possible they're crap. Same heads that work on newer cars will do fine for him, GT40 heads, GT40p heads, or E7 heads might be better, depending whats already on there. Could even go aftermarket and use AFR heads or something. What is he looking to spend, and how fast does he want to go?

      Looking to spend around 400-500 bux, he just wants something to get that big old thing up and moving a bit faster, nothing crazy.

          If he wants to do something vintage, I recently noticed a set of old 351W heads on eBay that should be a bolt-on deal with the little bolt-hole bushing things. I e-mailed the guy and he said the casting number was D0OE. Don't know if those were as good as the D0VE heads everyone talks about, though.

            I've heard good things about the D0OE/C9 castings. They are often referred to as the pre-cursor to GT40 heads.

              The D0VE casting is for a 429/460 I believe. The D0OE in stock form is a bit better than the E7, but not as good as a stock GT40 head. They have lots of potential though from what I hear.

                  here's the Cam info:

                  Crane Cam Part Number: 363902
                  --------------INTAKE EXHAUST
                  lift at cam :2847 3027

                  (*using stock 1.6:1 rocker ratio)
                  adv. duration: 260 272

                  "This car/truck will always be street driven.
                  I'm interested in increasing the low end torque,
                  mostly because it will make it more fun to drive. I'm
                  thinking of a budget of ~$600-800 for heads, carb,
                  intake, and other parts like an HEI distributor."

                  "Reman Cast Iron Heads

                  Stock 2bbl cast iron intake.

                  You guys think some rebuilt GT-40 heads, a performer intake, and a 600cfm carb would do it?

                    That combo should perform decently, but its not likely he's going to luck out and get all that for $600. I'd vote for leaving the heads alone since they're rebuilt, and doing the cam, carb, and intake. Heads will be the most expensive part of the swap, and if they're correct for 1972 heads, theres a decent chance they arent all that bad anyhow. That 2v iron POS intake doesn't flow for squat. My friend had a 71 Mustang with a 302/2v and it ran out of power by 90 mph. Engine had low end power but the intake system was crap. If he lucks into a deal on a set of heads, by all means go for it but being realistic, I'd probably leave them alone.

                    Oh, see if you can find out what spark plug that he's using in there. Might give some clue as to the vintage of the heads. Also see if he knows if they are adjustable rockers or the pedastal bolt-down type. Original should be big spark plugs and adjustable rockers. If its a later model head, it will likely be small spark plugs and pedastal rockers.

                      FYI, the guy with those D0OE heads e-mailed me to say he'd pulled them from eBay in favor of something he hopes will move faster, but they're still for sale. Says his name's Russ, reachable at russghull@msn.com.

                        Upgrading that ignition system from points to anything else will net an improvement in performance and gas mileage. It'll help any other mods along.
