Another opinion question
Also to if the smaller valves are kept in the heads the car will 60ft and et faster, the heads are a bowl cut earily casting with a valve job. They didn't do any porting to them, this is why they used the 2.02 valves as help out with the flow. But if the heads were used with the smaller valves and ported the head would be better than the head listed. That head only flows around 220cfms, and the race ported head flows 275cfm. We have already done better than this with 1.88 valves and better in the low lifts. The combos that they list will get you in the et bracket that they say and more, then if you have a good chassis you will even go faster with the same engine.
