hey guys im looking for a good set of turbo heads the bottom end is forged 5.3 bored 20 over so its 3.8 bore size.... Im trying to find a set of heads with a 72cc chamber to lower the compression but has valves that are not too big for the bore size so i dont run into any valve shrouding issues from the bore size being small...

I found these heads the deck thickness is great but just not sure about the valve sizing

72cc combustion chambers
1.550" dual valve springs

Thnaks in advance for any help

 

72 cc heads on 5.3 is going to be some very low compression

 

Besides the huge combustion chamber size, I'd be more worried about that 2.08" intake valve hitting the cylinder wall.

 

yah thats what im not sure with either... 3.68 total valve size... bore size 3.8 i want to lower compression huge chambers are good
