Is my 1" Phenolic spacer hurting me? and TB ?

[LX XLR8R]

282 with 2.02 is pretty big...i know the AFR heads with 282 made awsome power but you dont have AFR heads..another thing about the 282 is that it might too sick of a cam..(i.e. you are sopposed to use DFI or somekind of PMS with it)comps told my buddy that b4 when he was looking at it..and also rember it is allways better to undercam than to over do it..and with that much lift with that kinda heads your are looking at riding of the rev limiter and just about switching to solid cam instead of hydrolic roller..just some things to think about
