damn its a lot to read, seems kinda complicated, plus you gotta get a scrapped head, exhaust valves, buy their kits which they dont saw how to do. i donno i wanna do it but not if im gonna mess something up

i just bought some ported stockers yesterday for about 500, they have a 5 angle valve job new stainless valves .600 lift springs and lots of bowl and runner porting done, suposed to work better than gt40 p's and i can still use my bbk headers and my 1.7 rockers, and i have heard of na guys with stock heads that are ported in the 12's. so i think its worth it.

yea i know its just im so nervous, i really dont wanna screw up and **** my car up. So far its 150 bucks for a grinder (unless i have one or i know some1 who does) the kit from this company im reading a walkthrough from. I still gotta find a scrapped head to practice on,and junk intake and exhaust valves that fit my heads. dont know y i need those but it says i do

what is the gt 40 heads off surely not a gt 40 bc those are rare and they would not be easy to pick up from a slavage likei heard the were

definetley pick up some stockers and port them rather than taking a chance on screwing something up. Im not trying to post whor, just trying to emphasize this. IF you are going to spend hundreds of dollars on porting stockers, just buy some good used aftermarket heads. I just bought some aluminum Edelbrock Performers with 1.6 stud mount roller rockers for $650, not too bad in my opinion, and these heads have been shown to bolt on 78 hp with a mild comp cam. Just my 2 cents, I understand what its like to be on a budget though, hell if you can get a 40hp gain on some well ported stockers that would be great as long as it didnt cost you a fortune.

gt40s OGs are easy to come by they are on 96 and early 97 exploreres. in 97 1/4 they swapped to gtps

i know, but im not looking for aftermarket, im buying AFR's when i get money, i just wanna get a little extra out of my stock ones for now, so i just wanna port them, i heard about a 3 angle valve job? whats that about any 1 know?

StangerGT

a valve job, is where they put angles on the valve seat and match the valve to the angles so when its starts to open it begins to flow sooner, allows the flow of air and fuel into cylinder faster. if you want a valve job done i recomend a shop do it that has the right machines and know how. a valve job usually is more important than porting in alot of cases, the faster the a/f swirl in the more power youll make.
