I'm rebuilding my 95 7bolt and want to go with wieseco 1400hd evo8 9:1 pistons and seen that the only difference between the two on the chart is the head cc's 47 on the 7bolt and 43 on the evo8-9 piston and the gasket thickness on the 7bolt is 1.1 vs the evo8/9 0.86. What would these two factors affect (valve clearance /will need an evo head gasket/wrist pin off?)?
