gt40 vs gt40p

[rauscher89lx]

alright im new to this forum, saw this topic and thought it might help, and your inputs may give me a better idea of what im trying to do. i recently bought an 89lx, it now has 93000 miles on the stock 302. im not trying to make it crazy fast, but pretty quick and sounding right, would be nice and heads were my next step.

list of what i have done so far...
373s
subframe connectors
lakewood shocks and struts
lakewood upper & lower c/as
performance rotors and hawk hp pads
underdrive pulleys
bbk cai
shorty headers
catback exhaust...

i plan on removing all my smog shit, cutting my cats, and throwing an xpipe and new mufflers to beefup my exhaust.

i just pickedup a cobra intake that hadabout 1500 miles on it, brand new tfs1camshaft, brand new 70mm accufab tb, brand new 75mm powerflow(or something like that) maf matched to 30lb injectors..
and now i have a couple offers from locals with a set of iron gt40heads, completely re done to make them pracitically brand new 400$, and gt40p heads 450$ ( but i can probably get him down to 400 as well ) do i buy one of those? or pay an extra couple hundred and get an aluminum set? do i need to get roller rockers, pushrods, springs or anything i like that?

im hoping ill be hitting somewhere close to 290 - 300 hp? if not what else can i do, or change thats not to unafordable.
