exactly what larry said. The only reason i could see that you would wana take your intake off is to see that both lifters are completly closed, but knowing what stroke at least on of the pistons is on before you start, and your firing order, should make valve adjusment just fine with the intake on.

Aaaa... I dont know.. well, sometimes you can get away with just swapping out the pushrods, but on high mileage engines you have to worry about the new pushrods going through the rockers. Would replace the pushrods, rockers, and fulcrums/pivots. But who knows, it might work out fine.

while your at it and if you have the money, go for the full roller rockers. There was an article awhile back about just using roller tip rockers and it said they did'nt help much. While the full roller rockers freed up something like 15 HP. Think the article was even in a post here.

Anyway, cool, good luck!

got them sittin here in my hand allready, i went with the roller tipped because i could get them in a 1.7 ratio

there are alot more things i need to worry about as far as performance/economy before i start reducing friction
