i have a 350 engine i am planning on building it up and puting aluminum heads on it and running nitrous. I am just trying to get some input on what you guys think i should put in for internals and what compression ratio i should be running. Thanks guys oh yeas the engine is carborated also

 

you don't need aluminum heads find some good 39470403947041, 3947041x or 3927186. for your CR 10:1 is good. I suggest buying the book "how to build max performance chevy small blocks" by David Vizard should be able to find it at auto zone, Checker or another auto parts store.
