90LX50

O.K. I have my tax return, 2K.

I want to upgrade my heads, install a cam and replace my flowtech headers with ceramic BBK's. I have the cam picked out, E303 and I'm going with ARP studs. The heads I'm looking at are the World products cast iron set. I also plan to replace the timing chain set and water pump.

Would these heads be overkill for a street car? The reason I ask is this, these heads are $1,100.00 a set and I don't want to get more than I really need.

They also have sets that are less expensive with 58cc cumbustion chambers and single valve springs with 160 cfm runners.

I know that there are more expensive sets out there, but i'd like to stretch my 2K as far as I can without being too cheap in the wrong areas.

Any thoughts or ideas??

Thanks

naw, just World product heads in general, you can take a look here:

Good guess huh?

The 64cc combustion chambers will give you a low compression ratio. I was looking into these heads for a supercharged motor a while ago. I got very mixed reviews on them. Some people on other forums claimed they had to bring them to a machine shop and have some work done to them to even be usable.

the heads are nice and all but they have a few drawbacks like they are cast iron. thats 40 lbs you could remove from your FRONTEND if you went cast aluminum.

the numbers on those heads arent really anymore impressive than a good set of AFRs or edelbrocks. and these ones are aluminum which in itself, the frontend weight reduction helps out more than the power they add when it comes to launching IMO.

you dont wanna get more than you need, those heads would indeed flow more than you need with the 200cc runners.

in your case, i would put down 1250 for a set of AFRs, they probably flow near to those heads even with smaller runners (165cc) because the AFRs much higher quality, this helps velocity and low end torque too.

Check out the edelbrock performer rpm heads. They have similar specs as the ones dbeck mentioned and cost only about $200 more than the ones you are looking at

Will do, so i should look at 58 cc cumbustion chambers and maybe 160 cfm runners?

the gt40x heads have 178 intk. runners and 62 exh. runners. They're only 1.94/1.54 but u can bore them out alittle if u want. And they're approx. $1,250 for a pair
