well as some of u knew from another post i did, my red SC, newest one i just got, the headgasket went, now i stole my exhaust from my blue car, (high flow downpipes SCP + 2.5 to 3" to 2.5 SCP also) now i'm getting a set of exhaust manifolds ported from tbird 88, now i had a set of extra heads from my bro that he gave me, so i just had them pressure tested and plained, there fine, and i just gutted one took out all the valves, now i started to port the exhaust ports on 1 head, now i want to leave the stock cam and stock valves, but have a little more power, maybe put in a 10 % pulley, i think i remember once reading that not to touch the intake ports on the heads, just port the exhaust side is this true ? i've opened the exhaust ports alot, just wondering if it would make sense to open up the intake ports as well a little or not ? also my bro told me to get some compound and put the valve in the whole and spin them (i guess a way of cleaning them) is this the correct and only way to do this ? whats that stuff called ? well i took some pics last night (below), i worked on them for a few hours already, and went threw a few dremel bits, also whats the best way to smooth out the ports so there not grooved ? machine shop ? here are some pics i got yesterday, i got new valve springs + valve seals for these heads, can i clean up the stem of the valve with a dremel wire brush or should i not touch them ? they have a little build up of black on them ? Thanks Alex L
