I'm also curious why you went for a saab head but not liners? I thought the stock head was good for 600 bhp? Are there benefits I'm missing with the saab head?
The biggest issue I personally have with the z22se head is the taper spark plugs, due to the design of the head the spark plugs can crack the head if over tightened :thumbdown:
the saab /lsj head uses flat washer plugs 😃
But the real reason for using the saab head is it's much stronger than the z22se head as it's 'sand cast' rather than 'lost foam' :thumbup:
also it's designed to work with a sc inlet manifold
The reason I have not had liners fitted is that I was asked to build a reliable 350 bhp engine, so liners are not required.
If the engine's owner wishes to increase power over 400 bhp at a later date then it's not a difficult job to have the liners fitted, the wiseco pistons can be retained.
