i can buy heads cheap at yunkyards around here... lets say i dont wana port them or anything, wish ones would be the best for my setup i have right now?

 

anything you buy other than what you have is gonna have to be milled to keep your compression. 799 of 243 would be your best option as far as stock. or buy some like you have and have them milled to up compression.

 

lets say i would have them milled.... wish would be better: mine 862, 799 or 243?

 

799 and 243 are almost the same. they also flow better than the 862's. you will have to mill more off the 799 and 243's to keep compression.

 

ok sounds good... will there be a good gain if i get them ported? and how much does that cost?

 

always a good gain if the portwork is good. for the price i would look into these.

you would need to mill them some but could reuse you springs off of your heads. should pick up good.
