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?

Any suggestions?

Edelbrock,merlin.

Or You Could Go With The Gm Performance Zz502 Heads.

I've noticed many Dart and Brodix packages as well...

Planning on keeping my stock roller cam for now..

What's the scoop on Zz502 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.
