HI Guys

I finally pulled my head bolts as im adding weistec bolts

They seem in pretty good condition compared to the ones ive seen previously

the first pic are the worst ones

I think all in all they held up pretty well considering ive been making 600hp for the last 15000kms and running multiply 10sec qtr mile passes

No corrosion on them.

Jasonoff

How many km on them in total?

What does the inside of your intake manifold look like? Notice any other unusual wear while you have it apart - cams, lifters, etc?

Nice I'm doing the same soon, what do the ports look like? Contemplating having them cleaned up while the heads are off

Merc63

Intake manifold, ha ha, what is one of those? Mr747 runs a blower.

You can see inside the ports on the head, looks damn clean to me, hes probably running a catch can and I bet boost helps keep it cleaner.

BLKROKT

Ah ha, duuh, of course - my bad.

Would be interesting to hear how the lifters and cams look anyway.

mr747

engine has 80000km

lifters and cams look brand new only has one slight problem when we pulled it down

Here are the pics

Looks like there is some wear here

mr747

here is some pics of the head and cylinder

Looks great

Porting heads isn't to clean oil and dirt... Rather smooth out any rough surfaces from the casting... Some castings can be made to flow considerably better after (more hp)

mr747

I was going to port the head but the wait is just to long and right now the weistec heads are just not in my budget got so many things going on at the moment

so they will be cleaned crack tested and put back on with the new head bolts sls buckets arp gear and then back to the track with a stage 3

I saw you wrote you were also going to remember to change the buckets with the SLS ones.....good job.

Also needing to swap out my head studs this summer. Where's the cheapest place people have found to purchase the sls buckets, head studs and new head gaskets.

Merc63

I know what porting heads is. I have a Stage 3 car I built myself You said cleaned up...I see what you mean now.

These heads flow really good from the factory, I doubt you will get much from polishing the casting. Usually a slightly textured port flows better than a really smooth port. With a really smooth port the air can stick to the surface.

The CNCd heads are way too much $$ for the gains. Build the engine and run most boost.

mr747

So true mate 5000 usd for 50 hp 100% not worth it unless building the engine

BLKROKT

I'll port your heads, a lot, with my Dremmel tool for less than HALF that. PM me if interested.

I miss the good old days..... actually I'm only half-joking here. Some light port-matching to the gaskets might be fairly non-invasive and worth a couple of hp while you have it apart.
