92 Toyota truck ls1 build many questions

[americanracing20]

Building a 92 Toyota truck with a 5.3 from a silverado. I want it to be streetable but also very track worthy. So here we go I want to either go 383 or maybe stoked bigger not a set thing yet. Prob use the double comp valve springs I have good to .650 lift, possible ls7 lifters if I can not sure if that application will work. Will prob go with Texas speed heads. 42 Ib injectors and I'm thinking scorpion rockers. Need to know Wht y'all think about these ideas. the motor will be naturally aspirated no boost or nitrous. Any input on parts is appreciated need ideas on the whole assembly. Looking to have upwards of at least 500 hp.
