Thanks Terry, i had trouble finding that on your site. Can you tell me the flow #'s at .550 lift on those. My goal is to hit 400rwhp with a TR230 in an A4 with a high stall,headers etc. Those should do it shouldnt they?
Thanks again, Tony

Why are the 97-98 heads cheaper? Is there a performance difference?

Performance is the same other than the 97-98 heads will have less compression. One thing you could do is get them decked if your running a camshaft that allows for decking We offer both the 5.3l heads & 5.7l heads & I have 5.7s in stock

What is compression ratio on PP $1295 stage 11 5.3 heads ? Also do you need new valve covers or will the stock covers work with these heads ? Anyone ?
