    I have been running stock heads that I ported but I just put on a set of Sportsman ll which should increase my HP and torque by 40-50. Next is a gear chage to 3:55 and should be able to get into the low 13's with it.

    I.M.O.,those heads are about 3 sizes to big for your 305.
    Did someone recommend those large heads??

    Eric My engine was bored to 315(not much bigger than stock) but a friend of mine who rebuids engines gave me a set of world sportsman heads with 190cc intake runners and 72cc fast burn chambers. He said they should work with my engine. I hope the hell there not to big because I really don't feel like changing heads again in my cold garage.

    I am not sure what heads you have.
    World Sportsman are not 190 cc's they are 200 cc's as cast.
    I don't know of any cylinder head company that makes a head that has a port volume of 190cc's.

    Eric Your right. I was going to buy a set of AFR high torque cylinder heads which are rated at 190 cc, but got these for nothing except a trade for a set of 327 heads. They are 200 cc like you mentioned. Are they to big for my engine?

    Yes,the 200 cc heads are to big.
    I would think a set of Dart Iron Eagle heads with a 165 cc port would be much closer or a set of World S/R torquer heads with a 170 cc port volume.
