valve size 
I really don't know exact flow differences, but with the bigger bore you have you would be leaving at least 20-30 rwhp on the table. Bigger valves are not that much, I would think they would be well worth the $$. Call one of the sponsors and see how much they would charge to switch them out, and what there opinion is of the power difference.
I think I have talked to you on the phone before. If you put that 402 in around the first of the year last year. My name is Keith and I had just bought a resleeved block. I think you may have been helping Tommy put a ring and pinion in his car. I know T. very well myself. Next time you talk to him, tell him that someone told you to call him T-bucket.
Love the Shineyham video, Tommy showed it to me on the net.... I LMAO

Thanks for the info!That was me at Jonny's shop. I was using stock 5.7 heads on my 402, the car made pitfull power, fell off to early. I am sure ported 6.0 heads will be better than stock 5.7 heads, even if the valve size is stock.
