gt40p flow numbers question

[drewzx3]

Alright im thinking about buying some gt 40p heads and plan to run them with my mods below plus 24lb injectors. My goal is 275rwhp. I dont know anything about flow numbers so here they are below. Should I be able to reach my goal with these heads?

Valve Lift-----IN CFM----EX CFM------% of EX TO IN
.100"-----------65--------64------------82
.200"-----------121-------110-----------71
.300"-----------171-------105-----------72
.400"-----------199-------141-----------70
.450"-----------195-------138-----------68
.500"-----------196-------141-----------67
.550"-----------200-------141-----------67

Valve Sizes-----1.850"----1.550"
Test Pressure 28"
Test Bore 4.030"
Average EX to IN % .100"-.500"=71%

All test performed on a flow management 500.

I believe it was Grady who posted several power numbers with different setups. One of the better ones I believe was 296 HP and comparable torque with P heads, a cobra intake and an E cam, as well as exhaust upgrades like O/R h and flows or or some other decent muffler. There was probably also some tuning done but I think P heads are a VERY good alternative to some expensive aftermarket heads even in stock form. Have Thumper work them over and youll be really surprised at what "stock" heads can do.

you will reach that no problem with stock p heads, a good cam and a good intake

THe heads I were thinking about buying were ported.
