Somewhere in looking at head porting services I found one that will do a perimeter valve cover conversion as well. Has anyone else run across this? Who are some porters other than Lloyd Elliott as I don't see it on his site.

 

I saw some heads on Advanced Inductions website that had them so maybe that's what I saw the first time. I emailed them to see if they will do just that service.

 

do you have a good reason to waste money on that

 

You can also buy an adapter plate that will do the conversion. Or like my AFR heads which go both ways (center-bolt, or old-style SBC 4-bolts).

It's in a Nova and the centers probably dont match the 'era'. For me it would be a who cares lets save that money for something else.

The conversion plates usually are not that good. They will also limit spring and rocker are choices. you can not use a big spring with a conversion plate.

Converting the heads really isnt a big deal. Just need to add a little metal where the bolt hole are. Mill it flat, drill and tap the hole and bolt on a set of perimiter covers. Any head porter should be able to do it, or any fabrication/welding machine shop can do it with ease.

 

I never checked on a set of stock LT-1 heads, but on these set of Trickflow heads, I was able to just drill and tap them for this set of perimeter valve covers:
