What heads would be good for my x303 cam

I am running an x303 cam in my 88gt with stock e7 heads and everyone says I need heads to take advantage of the cam so I am just wondering what heads I should use that are not gonna eat my wallet as I am enlisted military and don't have gobs of cash laying around?

its hard for us to pick heads, not knowing if you are gonna have ptv clearance issues. thats a pretty big cam. so if you add larger valves to the equation it can be tricky if you dont have properly knotched pistons. usually you select a cam around the heads. whatever you choose make sure you check ptv(piston to valve) clearance.

trojanhorse is running edelbrock heads with an x303. either edelbrock, afr, or trickflow would be my top choices. you may have the best chance of running the trickflow 170 heads. thats because there valves are more centered in the combustion chamber, giving them a little more clearance when open compared to others.

also it would be a good idea to upgrade throttle body,24 lb injectors with matching maf, and intake.

I am running a gt40 intake and 24lb injectors already getting a 65mm throttle body soon just need to get heads if I can find some cheap
I have been told to get afr I talked to a guy that would sell me gt40 heads for super cheap but I read they are smaller combustion chambers than the e7

yes they have smaller combustion chambers than e7s. i dont think there is anyway to run those heads without special pistons.

if your gonna get some heads you may as well save a little money and get some really good ones. a gt40 head may give you 20hp as a top brand aluminum set of heads good give you 100-120hp with supporting mods, which sounds like you pretty much have.

im gonna say you have the best shot at making the best power and having enough clearance with the tfs 170s. they can be picked up for a hair over 1k with your forum discount. but thats just a guess that they will work. i have .516 lift. and i have all kinds of left over room in mine.

AM doesnt even carry all the trickflow heads anymore. so no discount. but i would buy them here. http://www.summitracing.com/search/P...=trickflow+170

also, just cause i had lots of clearance, i just want you to be aware that every setup is different.

with an xcam? i know you have those heads with a tfs stage one cam right? because the xcam has quite a bit more lift.

Yes with 1.7 rr's I'm at .512 lift I believe,..now the x303 has a .542 lift with 1.6 rockers , if he's not checking ptv the heads I'm running are very good!! If he's gonna stroke it now or later the RPM heads I'd go with! IMO!

How much extra room did you have when you did ptv checks? Just wondering cause if you had a lot then that's good. The reason I recommended the tfs is because they have a different valve angle that gives them a little better clearance over competitors. But I agree that any that I stated (edel,afr,tfs) would be good performers.

It's good if you had a lot. But he's definitely will still have to check ptv no matter which route he goes.

I laid at least 3/16-1/4" of clay on mine and never touched it. I was suprised. I have b303 with 1.72 rr

You don't want to up your rockers anyways. 1.6 are fine. But you won't have room to go to 1.7s

Bottom line, do some research and see what different heads people are using with the X303 cam to be sure the heads you purchase will work. Normally I recommend the TFS/Twisted Wedge/Track Heat heads for single profile letter cam combinations. Your cam is big enough though that TFS HighPort / StreetHeat heads are an option that I would recommend.
