Converting 4 bolt heads??
Converting 4 bolt heads?? I know I have seen threads or posts about this before.
Anyone here done it? Or know of a Place that does?
I almost think the easiest thing to do would be to just build up alum where the tabs would be. And then drill and tap them before milling the head.
Bought aftermarket 4 bolt heads because was planning on using my ls7 block.
Well one thing led to another and now I am using a lsx block.
And hate to not use 6 bolt heads with it.
Getting new heads isn't an option because I already have the valve train planned out and heads already have jessel rockers.

I called around about the same thing, and it was cheaper to just sell the heads and get six bolt heads. It's 100 more for most 6 bolt heads vs other world cost to convert 4 bolt heads. Even with machine work for rockers, you're still in it less to get new heads.
To order new heads. With a comparable rocker system I would spend another 6k to 7k dollars.
So to say converting these would be wasting time, money, or cost the same as new heads is foolish.
Even if I spent 2k or 3k on converting these it would be better than buying a new set.
I also mentioned buying new heads was not an option. So no point in even bringing it up.
I have called LME twice and not got a phone call back yet.
If I hear from them I will see of they still offer it.

Rather spend 2k or 3k on these than 6k or 7k on new ones.
Even 4bolt I'm sure I can throw a ton of crap at these. But if it wasn't a huge deal to add the tabs I figure why not.
It's obviously possible and has been done by several people on lots of different heads.
Just wanted to see if anyone around had some insight or experience on it.
If lot I'll either figure it out myself or just not worry about it, depending on how quickly the shortblock goes together.

There is not a 4-bolt head in existence that would justify spending an extra 2-3 thousand dollars on them would make any sense to put on a 6-bolt block.
I'm not sure that's worded how I want to say it, but you get the point.
Please break it down for me, the 6-7 thousand dollars to convert to a 6-bolt head.

Trickflow doesn't make ls7 heads so that's not an option either.
Still, don't cut yourself short. Just save up some money, sell the stuff you have and bone up. You'll be glad you did in the long run.

The problem is anything welded on will never be as strong as factory cast.
So you'll spend a lot of money adding them, they'll never be as good, and there's the chance they'll break off.
So all the money could be spent for nothing.
1/2" studs would probably be a more cost effective solution
