Im building this motor an the disassembled the head. what was wrong with was a broke a keeper, an wore out the rockers. they said i need to upgrade the head for the more power. I see alot of people running stock with 400whp. i was only at 7psi. what gives? I dont really have the cash for new spring/retainers.

 

i have stock head i'll be shooting for 450-500

 

see...thats what im saying. wtf gives?

 

Matters your setup. If you have a set-up inefficient (log manifold, stock cams), ported head will not do too much for you.

 

once u port the head..its not stock.

i have alot of ware on my rockers an broke a keeper. only pushing 7psi. now the intake valve are screwed too. i dont get it. plus it was just rebuild about 10 (v-seals an regrided ect)

 

Stock cams ? Who rebuilt it, I mean someone reputable or yourself ?

 

reputable. i think maybe i was starving the head. i used the plug on the side of head for my tuebo T'd to my gauge also. Maybe that the problem?
