newbie engine builder questions

[kenfyoozed]

i have heard that it is best to build a stock 1600 engine fr your first engine, so you can see how everything goes together. i this a good idea?

also, would it be better to buy a kit from someone like SCAT, Bugpack, or someone like larrys offroador just piece the parts together from here and there?

would using any remanufactured parts at anytime be wrong? if so when shouldnt you use them and why?

i have an old engine i want to build from. i will be taking the case to a machie shop for inspection. if its good is it ok to reuse?

could i bumpthe 1600 up to a 1641. if i shouldnt why not? or should i jut go and build like a 1776?

what heads are good? 041, 042 , 044, eliminators? and what valves woud be good to use with what engines?

i know i have askd a ot but i want to do it right the first time!!!!

please help me learn.

thanks
