i personally did Long Tubes(Bassani), Mid pipe o/r x(Bassani) and cams (Comp cams Stage II)i have only spent 300 for the LT and O/R X and i spent 600 for cams... i wish i could do the heads but the gaskets and bolts alone are 300 for the heads...With the LT it only cost me like 50.00 for new gaskets and the cams it cost me 190 for new springs( Because the lift is more then .500 it was .550) But it was WELL worth it...So if i were you i would do HEADS 750.00 CAMS 600.00 LT 500.00 MID PIPE 140.00... Total 1990.00.... and still have some left to spend... ut find a GOOD shop in your area to install them..k thats my .02
