I'm pulling my heads to replace my lifters, was thinking about dropping my heads off to get ported or just buy the tsp stage 1 ported heads. Is it worth it for me to do either?

 

i have been running the stage 1 317s. Honestly, im not sure how much they helped they're cheap cnc'd heads with no chamber work. Only reason I put them was because original heads and a couple exhaust studs broke off inside.

 

Wow makes me think not to spend the $1200 then. Lol. I may just try to get them ported if I have the time (trying to make a car show). Looking to break 600whp at around 15 psi and on pump 93

 

utter waste of money and time to port for that low of power

 

Well I wouldn't mind more power, 600 is just a minimum goal I'd like to hit. I'm currently at 450 @ 11 psi. I just installed a jfr isky218 cam so I have to still get dyno tuned for that. I'm assuming that willful me close to 500. I figure turn up the boost to 15 psi will get me mid 500s. Still trying to figure out what to do to hit 600 though
