I'm planning to replace my stock cylinder heads (valve guide problem) either with a bolt-on unit or by having mine rebuilt with custom porting. I'm considering 3 options: 1) Edelbrock performer heads ($1100), 2) TPIS L98 stock head castings ($1250), or 3) having my stock heads (1987 casting) rebuilt with the necessary performance porting (??$). What is the best choice? How much would you figure having the stock heads rebuilt would cost? Are there other choices?

If you are willing to spend $1250 on TPiS heads, then pick up a set of AFRs and be done with it. :yesnod:

I recently sold my stock 166k mile 1987 cylinder heads on eBay for $450, so you will be able to reclaim some of your costs. :yesnod:

scorps correct get some AFR190cc heads, just the heads swap will gain you some hp http://www.airflowresearch.com/

For 150 bucks cheaper, I would definately go with the heads from edelbrock! :yesnod:

I have to agree with scorp508 on this one and go with AFRs. It isn't like you have to continually spend the money on heads.

If I had the cash I would go AFR in a minute. :yesnod:
