Hey guys, I have built a 383 stroker with nitrous that I am going to begin using for drag racing (not competitively but just for fun). The car is almost complete and I am beginning to think about the one part of my motor that could probably use an upgrade. Many years ago I ended up buying some Edelbrock Performer RPM aluminum heads (geez--like 15 years ago). I didn't really want to part with the heads and upgrade at the time due to funds--or lack thereof LOL. Now that I am older and have saved up some money, I could upgrade, but I am still wanting to cheap out. I am open to buying new heads but I just need to make sure that I am doing the right thing. My question is this: What do you guys think that I should do? 1) Keep the Edelbrock Performer RPMs for my SBC and have them professionally ported/port-matched. 2) Sell the Edelbrock Performer RPMs for whatever I can get for them (new they run $1,400 for the pair). These probably have about 2,000 miles on them and have never been hit with nitrous. I am not even sure what I can get for them. Whatever I did get for them, I would then use to buy some nice AFR heads. I'd have to do some more research on the right head. The current motor setup: 383 Stroker with all forged 4340 internals, H-beam rods, ARP hardware, etc Comp cams Xtreme Energy 284H Edelbrock Victor Jr intake Holley Ultra XP 750 Hedman 1 3/4" headers The motor currently has 10.38:1 compression. I've got it a secondary fuel system set up with race gas in it to help out the motor when it gets sprayed. It will see 250hp shots of nitrous. Car currently has E/T Streets, Caltrac bars, 3.73 gears (likely upgrading to 4.10s), a locker, and a roll cage. It should launch pretty well. I feel like I have spent so much money on the car that I am just leaning toward biting the bullet and buying some AFR heads (I am not even sure which ones at this point--going to have to read up) BUT if I can get the Edelbrock heads ported with similar power for a lower cost, I am happy to consider that too. You all are so helpful in this forum so I figured I'd ask. Thanks!
