Any shops doing head work? Power gains?

Need to do gaskets and studs in the coming month or two. Figure that while the heads are off being checked, I could have the ported/valve job if its beneficial.

Are there any companies out there doing port work or valve work for these heads? Any gains to be had with an otherwise stock truck with a headstuds and a headstud tune?

Always gains to be found when improving air flow. Probably see better gains with the intake done also.

depends on what you use the truck for...there are plenty of people whove done port work and bigger valves and what not, but the better question is...are the gains worth what itll cost. RCD has a CNC port work program they claim improves airflow 27% when used in conjunction with their exhaust manifolds. Other people have reported gains of 40-100 rwhp, but theres a ton of variables involved in how those jumbers were achieved or tested, if at all. The only one ive seen close to gaining 100 hp also had a bigger cam as well. Im in the middle of some testing now with all this, ill report back what I find...but if you are serious about port work, plan on spendind at least a grand on top of the other machine work necessary for a quality rebuild. To answer your question, if its a mostly stock truck, I wouldnt begin to waste the money on port work, Id put that money towards hardened valve seats to eliminate cracking, bullet proof oil cooler or a nice 3 day cruise lol.

Gearhead is right on with his info. Just porting the heads isn't going to achieve much to warrant the cost. The entire airflow path needs help to make all the gains add up.

Gearhead,

Thanks I am interested in your findings, I'm hopeful you have some kind of results for us in the coming months as I'd like to do the head work soon.

Wasnt really planning on a cam, so maybe the headwork wont be as beneficial as I had hoped. I just read about how restrictive the heads are and was thinking turbo+opened up ports = free'd up power.

I was figuring on about a $1,000 for headwork.
