Im going to be running around 10 psi on a built LS for a while and I was debating on what I should do to the head. Should I spend $600 on a vtec head which will remain stock. Or should I spend $600 towards a port/polish, crower oversized valves, duel valve springs, and titanium retainers? Which will net me more hp?

Another question- How high do you recommend me revving my engine to with the LS setup I listed above on stock cams.

 

go with the vtec head. I think you will be happier with the vtec head. The vtec heads flow alot better then the ls heads.

 

just p/p the stock head and get a stronger valvetrain. If you put a vtec head on your also gonna have to get a gsr ecu which is upwards around $300. Also without building your bottom end your just asking for trouble doing a half assed ls/vtec.

 

I dont plan on revving it higher than 7k until I do the bottom end. I will be going with eagle rods and 9.1 compression rollerwaves probably. I think that will be sufficient.

 

I agree with pureteg, p/p the LS head, build up the valve train and run some turbo cams... You will alot better off for the same price of "half ***" LS/vtec

 

Or just keep the LS head stock.

 

Somehow my adjustable cam gear bolts stripped which in turn retarded my intake and exhaust cam 20 degrees and bent all 16 valves. So either way I need a new head or new valves. Why not some nice stainless steel ones that are 1mm oversized?

 

Just FYI: Hondata can mod your ls ecu to run a vtech head for 100 last I checked.
