Heads for boost, valve size??? I am getting ready to order my heads. I am going with the Patriot Performance Stage II LQ9s. They are offered in 2.02 intake valve and 2.055 ( no difference in price )
What are the ups and downs of either???

I stand corrected. I wonder why we rarely see any companies offer a 243 head with larger than 2.055" valves? It seems when a head is available with 2.08" or larger valves, they're usually marketed for a 4.00" or 4.125" bore. Just a thought.

I would imagine it is because a large majority of people run N/A due to the cheaper costs. Valve shrouding would definitely become a concern and large valved heads are typically harder to cam correctly due to cylinder fill. A little different when your pressurizing the chamber past ambient.
