Anybody know where you can find the head volume, cc's, for the different 914 stock heads?

O.K. ... measure them
I have two sets of 1.8 heads, couple of questions Let's assume I am building a 2270 with a 78.4 stroke. I open up the heads to 42 x 36... is this enough for this engine starting with the 1.8 head geometry? ______ I run the CR calcs for a flat top piston, 0.060" deck height on stock 94's cylinders bored out to 96 and stock 55 cc combustion chamber... I get a CR of 9.6... a bit high. Need to go up to 60 cc just to get down to 9:1 CR..... dremel out the heads to get the xtra volume?.... do the main metal removal before or after putting in the new valves? .... haven't even gotten to chosening cam... this head/cam stuff is black magic to me. |
