Head mods

Quik---
Thanks much for the info. I've had preliminary discussions with the folks at Extrude Hone regarding the head work. My question has been as to whether to do a little work before sending them the heads. I may have some more questions in the not-far-distant future.

man Quik you know it all.

It does seem like a lot of work for a smaller gain

If I had a spare set Id do it for 20 at the wheels, I mean hell, it doesnt even look like anything was done to them.. :confused: Maybe some slight clean up by the valves but I dont see anything of notice that looks like its been "touched up"

Hmmm, thanks for the pictures tho Quik.

my exhaust manifolds and the intake manifold were smoothed right up to the gaskets also.
this was alot of work for not much gain, not to mention getting the mechanical bucket tappets under the cam lobes shimmed correctly is no easy task and can easily cause you to chew up shims down the road
 
THANX QUIK !!!! And....

I very much appreciate your willingness to be of help.

Just a thought to other observers. Porting is one of those things that work better as output levels go up. I would not make the effort to do porting if I was going to be satisfied with a cold air pipe and a Magnaflow cat-back. 20-and-a-little-bit HP is certainly worth having, but it's much easier to put one size larger jets in your spray than to remove the top of your engine in order to start work with rotary files and tootsie rolls.

As many of you know, I am (slowly) getting closer to assembling and installing a fresh engine that has internal parts designed to take the load from a pair of turbos and an elevated shot of methanol and nitrous oxide. Therefore, I am going to do all the other things that will help efficiency and that are relatively easy to do with a motor spread around on the benches and engine stand in the garage.

It's going to be fun!!
