I know that.....its around 10k for the 2jz.

The 7m should I go that route will have MHG and ARP studs for the head but I have to pay extra for that so it will prolly be more along the lines of 3800-4000 route.

I would keep the 7m indefinately if the parts for it will stay around for a long time. Being that its an 87, I'm thinking within the next 5-10 years the parts will be extremely hard to find if not obsolete in that you CAN'T find the parts anymore.
