hey guys, i have a brand new set of valves out of ls2 heads, and i was wondering if i could easily get the 706/5.3l heads upgraded to 2.00'' valves
i know i'll have to do some work in the chambers, but i don't really care to forego the expense of a whole new set of heads.

they used to install the 2.0 valves into the 5.3 heads but TSP found out that installing the larger valve actually hurts the flow of the head since the runner was never designed for that size intake valve

it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference
well that sucks, but i guess some porting wouldn't hurt it

With the proper machining work--I am sure you can have this successfully accomplished.
Doesn't TSP install 2.02" intake valves on their Stage 2.5 setup? With their researched machining/flow work, they get some damn good flow from 862/706 castings...Originally Posted by Quik

if you search in the GEN III section of tech for this type of post you will see two of the guys from TSP speak on this subject
