what are you trying to do? as far as i know theres only two diffrent rod sizes. std length and -2mm. as far as the deck height if i remeber right my 2 mill over had a deck height of 12 thousands.

Im trying to fit a zx14r head to a customised auto engine block and would like to know this info so I can work out a few things like compression on a calculator using an 88mm stroke and what the best custom rod is needed using stock piston will give me 1951cc.
12 thousands is how much in mm?

Your working with a 36cc chamber's claimed,( but cc them) on the 08 head,and with that stroke 27mm over 14's 61mm . I would definitely have Jim,or Bob do the wild thing with one of their big 14 heads.
That much stroke with stk bore is gonna need a lot more flow and probably gonna be the limiting factor in fill. Also i wouldn't go less then 5 in the hole on deck maybe a little more depending on how hard you plan on turning it. I am assuming steel rods,if alum, then open those spec's accordingly. 12 THS =.305mm 5ths =.127mm . No disrespect to your machine shop abilities but i would definitely get in touch with Jim @ cnc on here.............

Thank billeason and quick6 for the tips my machine shop abilities are wet behind the ears. So definitely read the cc is 36ml on the chambers but felt they where less as they are very shallow compared to the 42cc car engines ones I usually play with. Any idea on factory piston Dish/Dome CC?
I didnt want to bother Jim yet as Im still welding up the block to suit the head but will definitely be looking at some port, new valves, seats and valve guides.
Im trying to remain with a little higher rod stroke ratio on the 88mm stroker block and hopefull only need to spin it to just under 9000rpm for decent hp. The final weight of the engine will be almost 50kg lighter than a Honda S2000 motor yet be way more compact and make full use of the Quakka aftermarket support.
I wanted to see if the zx14r piston sits right at the top of the deck or just above it. Hence would like to know the height of the block from crank centre to top of deck.
I figured it would be around 167.5mm or 6.59 inches high
thats with 112.5mm factory rods, 24.5mm comp height factory pistons and 61mm stroke 1.844 Rod stroke ratio
while the 65mm stroke upgrade will be 1.731
The block Im working with is 223mm (8.779 inches) tall block so RSR of 1.756 using 154.5mm custom conrods
