1998 Mustang GT head options?

is it worth it 2 port out the stock heads? I wanna run a vortech supercharger at like 8 psi but if i do that i want the car 2 make power not just 300. my thought is port out the heads, stud the block and get cams and then supercharge it? will this make more power than trick flows cylinder heads (if i use trick flow heads i wouldn't supercharge it because it will blow up from 2 much compression) please help

On a 98 with stock pistons, the TFS cylinder heads will give you a compression boost, which isn't great for supercharging.
NPI heads like yours flow wonderfully when ported. They even flow slightly higher than ported PI heads, and you don't get the compression bump.

The 2 people I would recommend for porting NPI heads, since they've got them figured out are Renegade Racing and Modular Head Shop. You can't go wrong with either of those, they've got extensive NPI head experience.

I'm not really up on NPI cams anymore, but if you give Nick a call at Modular HeadShop, he also offers a full line of NPI cams, and is very good at picking cams for you based on your full mod list.

No problem. Don't worry, if you call Nick, he'll spend whatever time it takes to make you happy. I wasn't even buying anything from him, and just called to ask a few questions about valvetrain stuff, and we ended up spending over an hour on the phone, and I learned quite a bit.

If you don't have a working knowledge of how timing events work, sometimes he can get a bit above the average Joe's head on his explainations, but you'll know why he recommends something, even if you truly don't understand it........
