some of you guys put coolant lines off the rear of the intake manifold to keep out the hot spots off the rear of the heads where air pockets form.
i did some rerouting on coolant lines today and was wanting to restrict these lines which are 3/8" so they wouldn't flow much coolant, just let the air pass.
i took out the fittings which were 3/8" npt x -6 flare and drilled the inside pipe portion and threaded for 1/8" npt and installed brass plugs and redrilled to 1/8" for the restriction.
works good so far.
