D3VE-->C8VE

I dont know can i change those heads without having too much compression for street use, i think those pistons (Badger P-734) gives about 9:1 with those D3 heads, have anyone idea for that?
What kind of cam i can use with that 9 comp?
Im thinking comp 274 extreme or lunati 268/276 voodoo...or do i loss power with those , i dont want to learn by mistake i hope someone has done mistakes before.

Be sure the heads can accept the amount of theoretical valve lift which the cam will provide...

How about measuring the combustion chamber volume of both heads? I've used two different casting date cylinder heads on a project of mine and it simply required removing material from the cylinder head to equal combustion chamber volumes, all other things equal! What do the cam companies recommend as to compression ratio for their camshaft requirements? Post your application and expectations as to camshaft requirements, you will get plenty of feed back!

P.S. Good morning Randy.

Ok, it seems that i get decent price DOVE-C heads, there has machine work done and all moving parts new, i see them next week, those have 73cc chambers and forget to say that i have 71 block so it have that longer deck?
