Still going ahead with the Suzuki head. I'm using the Suzuki conrods and pistons and because the piston height is lower on the Suzuki pistons I will remove less material off the top of a 843 block. With a stock Suzuki piston the capacity will be around 940ccs. My crankshaft has been away getting machined for a few months now! Hopefully I will pick up a bit of stroke increase as well so may do better than 940 in the end.
