need help with heads and cams!
Please state the purpose of your car and power range desired.
street or street/strip or track only?
400rwhp or more?
Docile or aggresive?
Stealth or dragster lope?
Also list all the mods you have so far.
Before you do any internal mods, I would suggest you to do a compression and leakdown test to see the status of your existing motor, once the results are known, you'll be able to make a better decision.
