I am considering swapping out the HS2's on my Spitfire for a set of the European spec HS4's that came on the 1500's over the pond. Anybody have a set and manifold they might want to do some horse trading for? Have HS2's, 3/4 ZS, heads, blocks, GT6 engine, can powder coat your parts, tyranny's, wife's small dog, mother in law, what do you need? Marty
