How far can stock rebuilt head go?

[EclipticalGS]

Well, I had a 6-bolt block built, 6-bolt rods, new 2G pistons, Coemtic head gasket, ARP headstuds, mated with a 7-bolt head, oem valves, guides, springs, seals, retainers. I have 272's for it. I just want to know how much HP can this build hold you think?

Plenty, That is a solid build and it will hold alot of power.. The stock head is great for torque.

This is my friend Darrens car stock head w/ some 272s

Thats very nice looking Boost4u, so he had a stock head with 272's. But what was his block? probably all forged stuff for the boost hes running?? Thanks

Yah the bottom end is built, ross pistons, etc etc. AEM EMS and all the bells and whistles. It's a race car, not a street car. Not the way I like it but that thing has come a really long way since high school, well just after high school. I bought my laser from him.

Hmm. I had a chance to get a Greddy ems ultiamte w/ harness for $400. Missed out, although theres not much support anyway.

eh, you didnt miss out on anything, nobody really uses the Greddy tuning. ECMLink or AEM EMS is the way to go

IMO, the stock head is really held back by RPMs more than HP

Well, i was going to have the graveyard install supertech springs to give me the 8000rpm redline, but they're taking long enough as it is and I think the stock redline is sufficient for me. Thanks!

I'm hoping to get similar results too, i just built my bottom-end with eagle rods, ross pistons and i had my head done with bc springs and retainers hks cams, bronze valve guides.

thats not similar, you head has BC springs, valve guides, retainers.
That's already better than my build by far.

I was kind of wondering the same thing. That video def. answered it pretty darn well. He broke 10s on a mostly stock head I think is impressive.
