I agree with dr_bowtie.Even though the 882 heads have bigger valves ,it is not a good trade-off. Besides with the combination you have bigger valves is not a plus. You can certainly use your stock manifolds,but if You dont have dual exhaust that is where I would start.I wouldn't put any bigger than 2&1/4 pipes back through the mufflers. If you're on a tight budget i would buy Summit !4.95 turbo mufflers. They work pretty well. I would Try to do my cam ,lifters,timing chain and gear set, intake and carburator all at the same time. Make sure the used carburator is good before you go wasting your money.
