i have a rebuild explorer motor in my old falcon and the heads are giving me fits. i have rebuilt them twice and for some stupid reason the exhaust seats keep warping and not sealing after about 300 miles and give off the sewing machine noise about the same time. they WILL be going into the scrap iron. i have been looking for economical replacement heads that will yield longevity and similar power.
i am stuck between edelbrock e- tec, iron rhs and for for x306. so far im leaning toward the fords due to i can reuse my rockers(scorpion) and the valve covers should fit.
the engine is basically stock with an ho cam and 70mm tb. i tried a trickflow stage 1 and it was a little too temperamental for me. 250hp that runs stock like and quiet is my goal.
which heads are normally the least problematic for the long haul?
