keep us posted!
Making sure you use a 0.040" quench will ensure the bolt holes line up.
The deck is 9.025" from the centerline of the crankshaft.
The stroke is 3.480" (1.740" is 1/2 the stroke)
The rod is 5.700" long.
The piston pin to the deck of the piston is 1.560" high from the centerline of the wrist pin to the piston deck.
The deck height is 0.025" from the factory and the stock steel shim head gasket in 0.017" thick.
9.025 - 1.740 = 7.285 -5.7 = 1.585 -1.560 = 0.025"
That 0.025" is the factory deck height. Add in the 0.017" + 0.025" = a quench of 0.042". Keep the quench where it belongs and the manifold bolts should line up. Changing the Piston Pin height and compensating in the formula will work out as does changing the stroke, rod length etc.
