Buying head for rebuild

[david-b]

Hey all;
I'm buying Travis' head off his car and I'm going to rebuild it. I've always wanted to do this, but I don't know where to start. I want to get it ported and get some kickass flow. I know its oging to be expensive, so I'm not doing anything for awhile yet. But can someone point me in a direction to look at? Like parts, and places to get it ported. Thanks!!

Anyone??? No info??

Do I need new head bolts then?

Where can I send for porting?

Do I certain valves and springs then for after the port?

Yes you'll need new head bolts.

I ported my head myself, it's actually quite easy.

Just don't get port crazy and port it TOO much.

I used a variable speed die grinder with an assortment of different bits. You don't need to replace any of head components. Actually Hahn has a 420a doing 10's on a stock head! The 420a heads are actually quite strong. I think I'm going to throw in some cams when I get to working on mine again, but for what you want, you shouldn't need to replace anything.

I'd cam the bitch if I were you. I dont know 420a heads, but I would go with some better springs and retainers so you can rev it out a little and not have to worry about valve float.

Very nice Travis

So I can use the stock valves and everything even after porting?

Yepp. If Hahn uses the stock head on a 10 sec. boosted car, I think we can use the stockers on just a ported head.

Woohoo, post number 1600 baby. Only 400 more till 2k.

[david-b]

But arent you making the holes bigger? How will the stock valves and all still fit when everything else is bigger. Seems like it would all fall apart.

[gthompson97]

No, don't make the valve ports bigger, just the intake and exhaust ports. When most people port heads, they usually just port the intake and exhaust manifolds. I don't think I've ever heard of anyone porting the "valve ports."

i need to sell a 1g head

[david-b]

Ahhh... i had the wrong idea then. So its just the intake/exhaust runners then? I can't wait to get this going.

Here are some things you can do to your head if you want


- Polished Stainless Steel Valves
- Bronze Valve Guides
- New Valve Stem Seals
- Crower Valve Springs & Titanium Retainers
- New Rocker Arms
- New Hydraulic Lifters
- Performance Valve Job
- Head resurfaced
- Intake Porting
- Combustion Chamber work

Its pricey, but you don't have to do everything.
