Would these heads work on my 99 5.3? instead of me having ls6 springs, studs installed in my stock heads. would these be the same > Scoggin Dickey Parts Center SD8926C - SDPC CNC 5.3L Cylinder Heads | SDParts - 1-800-456-0211

I would like to have and ls6 cam with these heads and the 7.450 Pushrods.

seems to be a very good setup for boosted applications.

 

They will most definitely work for your truck! They are in stock, ready to ship!

 

I was just talking to a couple people today about going with worked heads and using too large of a valve. I think those heads would work very well with a stock bored 4.8/5.3. Just for the record, this is what a 2.02/1.57 valve looks like in a stock 4.8/5.3 bore. I think I went too large when I did my 5.3, but they look very good in my 6.0 cylinders.

 

Awesome! What else would be different from my stock heads? The valves? I wanna turn my boost up without having a problem with valve float.
