So i blew up my blower 496 as seen below
it has all good parts in it, except it is still just a gen IV chevy with the same Iron heads, not even ported. I have the motor apart and might just port the old heads since they arent in bad condition at all. Or should i opt for a set of aluminum heads with a new cam to better suit the increased flow ill probably get. Also is anyone interesd in a pair of iron heads for a 496? Im saving the block, boring out to .070 new pistons bearings seals, will have on dyno soon. Just need to decide on heads.
Any input i'd appreciate.
