[s-cars] Want to do some head work.

[djdawson2 at aol.com]

 Just do a good valve job.  IMO, doing more than that is just a waste of money.  With a stock head and a standard valve job, I was easily able to get over 440whp out of my engine with some different tuning and a bigger turbo.

In other words, I don't believe that the head in the "constraint" in your power goals.  With RS2 components, you may reach about 325whp, well short of a figure where the head could be considered the limiting factor.

Boyz,

After slowly gathering my parts and pieces, I am nearly ready to put
on my RS2 stuff.

But before I do, I want to do stuff like replace the valve stem seals
and guides, possibly the lifters, and other stuff "while I'm there" -
stuff like timing belt, water pump - all the really great stuff that
will need to be done anyway, but might as well do it all at once.

I have heard that folks sometimes port and polish the head to get that
extra few percent, and I'm wondering if it is worth it for just an RS2
build, or just stick with refreshing the head and skipping the machine
work.  I also have heard that giving the valves and seats a fresh
lapping helps keep things nice and tight.

Peanut gallery comments aside, give me the straight poop on porting -
worth the money (plus shipping) or not?  Lapping/grinding valves and
seats?

If so, I need to know of a shop that can do the stuff with the care
required - no hack-jobs wanted.  Careful work done by experienced
professionals.

Thanks,

Eric
