Hello everyone, The other day i heard a chuffing sound coming from the engine bay turns out cylinder number 8 has been helli-coiled and had failed and will no longer do up, so i will be getting the spark plug tread re done! i need to replace the valve seals anyway as it smokes now and then. so im taking my heads to a local engineers is it worth getting the heads ported and polished its quite a expense but from what i have read up about other v8's being p&p there have been sizable power gains i was thinking it would be rude not too while the heads are off? has anyone had there mercedes m116/m117 engines p&p or know anyone who has?
Many thanks
