What kind of heads?
I'm looking to upgrade my 1995 502 EFI with 350 hours on my 25 foot Formula LS....
Everything is pretty much stock now with an M-1 Procharger..
She runs great. 70 MPH at 6500 Feet.. 75 at 3500 feet..
I'm also going to upgrade exhaust manifolds during this phase too.. Probably SS marine, Gil or EMI Thunders..
I want to go with a good quality aluminum head.. What would you guy suggest? Most packages I've seen start at around $1000 to $3000 with valve packages included.. Is it mainly a name brand thing or is there truly a quality difference?
Is 100 horsepower a realistic goal with the exhaust manifolds and heads?

Go with AFR's in either 325 or 345. AFR make a great performing and finished head! Don't forget to change the cam its a big part of more power. You will most likely still have to make some changes to the procharger settings but 100 hp should be realistic.
