new heads time

[falloutman2]

well i still got my 72 302 w/351w heads and the damn studs are pulling out now bc of that i have so far 2 bad valve guides (leakey vaccume :( ) so i was lookin for some help picking out new (used) heads id like alum heads goin to put 1.6 ratio rockers on it and maybe flathead valves lookin for something around 2.05 maybe 2.10 max its drivin a lot and i like to save some gas was going to rebuild my cast iron ones but it has seem to be a lot cheaper just picking up some new ones or hell if some one has some slightley used ones 351 that is for a good price and what im lookin for im hopefully not to pickey and i would like them to fit on my hooker comp headders as well port and polished i was thinkin as well car runs a constant 180 so i dont think i have to worry about warping alum heads so any and all advice will be welcome also was lookin at these roush 200 on craigs list

I would go for it espically if they are really ported. A really good port job can cost 800 bucks.

There are plenty of different AL heads out for a 302. They fit better than 351 heads and give more HP,mor5e compression more MPG.
351 heads are not the way go unless you have a 351.

well i have allways had 351 heads on my 302 just kinda reluctant to change i guess just lookin for some people to point me in the right direction of what i need like i said im putin 1.6 ratio rollers (no more stock crap) screw in studs and would like it ported and polished to match my alum intake and i belive flat head valves please excuse spelling and i think everything is matched up to the heads i have now just lookin to drop a few lbs and roller and screw in studs but check that craigs list link tell me if its a good deal or not

One thing to remember,302s use 7/16 head bolts
and 351s use 1/2 headbolts.Most of your aftermarket heads
are 1/2 so you will need either 7/16 threaded 1/2
headbolts/studs or the adapter washers to use the 7/16
bolts/studs with the 1/2 holes.
Looking at your sig,a used set of AFR 165s or Edelbrock Performers
will do you nicely.
A 2.05/2.10 valve is way too big and will ding a piston if the valve reliefs
are not cut the right size.The 2.02 intakes on those Roush heads will not
clear unless your pistons are cut for 2.02/2.05 valves.

well i have 351 heads form 71 on it now i have allways had them on it even when i got my car i thought the only real diffrence were the valve sizes from 351 to 302 i dont mean to sound ignorent but im kinda learnin as i go i also looked at them and talked to the guy with those roush heads they bolt right up to my block and wont have any clearence problems so... i dont know but still lookin and dont know if 800 is a good price for cast iron pair
