I am swapping my B16a head onto a B18b block and was wondering who makes the best block saver. Is there any special thing that needs to be done to install or do they just press in. I am putting in a low mileage B18 and dont intend at this stage to modify anything other than the block guard and ARP rob bolts. It will be a daily driver and will modify more when its time for the turbo and nitrous. Anything I should look for in doing this setup? This will be a temporary motor until I sleeve/rod/piston the B16.
