If you have the coin AFR165 Heads or Stage1 Ported Trickflow Twisted Wedge Heads from FOXLAKERACING are the single most effective performance power modification you can get for your heavy SN95. I recommend the AFR's for dual profile cam setups and the FoxLake TFS/TW heads for single profile cams. For example the stock cam has a .444 intake lift and .444 exhuast lift, this is a single profile. If you decide you want a aftermarket cam with a dual profile, where the cam intake/exhuast numbers are different, the afr 165's are the way to go. Also some aftermarket cams are single profile as well. Add a set of 3.73 or 4.10 gears. The 3.73 gears are best for manual street duty cars and 4.10 gears are best for automatic street duty cars. Between the heads and gears you will notice about a 1.5 to a full 2 second drop off your 1/4 mile times at a 1/4 mile track, which means aside from adding a power adder like a supercharger or nitrous
these 2 mods are the single most benificial mods your car will receive. You could chase 260hp by buying multiple mods but you will probably end up spending more money than you would on just the heads I suggested in the first place. You could use a different and cheaper set of heads to acheive your goal but the ones I suggested are the best the aftermarket world has to offer for a stock or modified 302 windsor and will respond better to any future mods as well as give you considerable more power than their competitors all by themselves, with heads you get what you pay for! Note: Adding gears wouldnt be required but doing heads/gears together is the single best performance gain your car will ever see. Note if you get AFR heads make sure they are the emissions leagle version if you entend to pass a smog test.
