the replies thus far, i'll continue to hear some more... =D I added some more pictures that might not tell you anything else, but i thought they were already uploaded but i guess not. So, Phil, your idea sounds like what i was thinking, and yeah, basically i'll probably end up saving my whole 74 engine for rebuilding at a later date. But for later this summer, I've also got a 75 motor that i'll clean up and get decked probably and stick the cleaner head on it with an 030 gasket and a new D cam and what not and call it good for now. That should be enough of an increase in power and efficency over my current setup of a 71 b20b with 42mm intake valves and what i suppose is a C cam that seems to stop pulling above 5k rpms... Not fun... So, a tighter squishing D cam engine with 44mm intake valves and my lightweight 8bolt flywheel and i should be having some more fun i think.

So, should i have this cleaner head resurfaced before i install it though? I think if I go this route(the one above) all I have to do is have my block decked however much i find i need to by looking at how far the pistons come up in the 75 block as is, and the head resurfaced and then get a new cam and lifters and associated stuff and a new timing gear setup of my choice... Thoughts?
