So I had a minor issue with my engine.
Minor being that it dropped two valves and destroyed a piston and I'm pretty sure the head...
So I'm looking at other options, and one idea was to run some quad AVCS heads, if I can source some, from a late EJ207 or something along those lines.
I'm going to assume this has been done before, and I understand it shouldn't be an issues mounting to the 20G block, just ensure I get the correct thickness head gaskets, and to use a set designed for the 20G.
The one thing I'd like to confirm is clearance for an intake manifold, and which to run?
Obviously I wouldn't be able to run my early manifold since the bolt pattern changed, but what would be the best to run and still fit under the RS bonnet?
Also happy to take other suggestions for heads to run
