i am building a 347 and wondering what heads to buy and will i be able to use my existing longtubes, the only other thing that sucks is that i dont think i will be able to use my roller rockers (i just got them a year ago) cause they are for pedestal mount heads and im going with stud mount, unless any one knows of a way i can still use them.

my items so far consist of a polished typhoon intake, polished tb, maf conversion, 24# inj, cai, hd trans, 373's, underdrive pulleys, long tube flowtechs catless H and flows , king cobra clutch, sub frame connectors, upper lower control arms, alum drive shaft, chrome oil pan, hv oil pump.

stuff im planning on buying...alum rad, bump steer kit, lower a arms, polished water pump custom cam prolly comp cams....other interior things

iv got a ways to go but i hope to have it done in a couple months

im sure that im forgeting somthing, but anyways im wondering which heads to go with twisted wedge or edlebrock rpm's. im thinking with 60cc and 2.02/1.60 valve

any input is good input thanks in advance
