I had heads that flow very similar to those. With a 90/90 1 7/8 lt's and everything else.... 238/242 xer 10.1/1 a4 c5 452 rwhp.
I switched to AFR/TEA stage III's.... 505 rwhp/473 rwt at 11.3/1

Those heads would work ok but the problem is if you set up an engine to use them with the samll chamber then decide you want to go to a Stage 3 truck head or a 225 AFR head then you will not have enough compression with the larger chambers they come with.
Also our 5.3 heads ussually flow about 15-30cfm less than our stage 3 heads. This is especially evident in the midlifts numbers.
