Default need help with head selection for 427

so i made an error with my 427 build I have a bored and stroked 6.2
4.065x4.125.-8cc pistons
I finally got all my parts in ready to put it together realized I made a mistake. I have a set of ported 243s I put new valves springs you name it had a fresh valve job and deck done on them. luckily Reckart caught my mistake. My 243s will bump my compression way up like 13 to 1 and I wont be able to run on pump gas. oops . so he told me to go with the l92 heads and intake setup. unfortunately i do not know much about this as Ive just studied ls1 stuff. from what I have seen l92 stuff seems to be cheaper. I'm just wanting any help or suggestions or warnings anything you guys have as I do not want to make another mistake. also is the ls3 intake compatible with l92 heads? which intake flows better etc? and what throttle body should i look into? sorry for all the questions. but I'm playing it safe this time.
