Before I start, please accept my sincere thanks to all of you for your advise and suggestions. Its nice to know that I can relate to someone or something even if it is on the net. Thanks all!
Now to my biggest problem- HEADS
I have a low mi 318 LA from a 71 truck. I would like to get about 300 hp from this if I can without spend my 5 childrens college funds! LOL
I have heads that are pre-unleaded fuel. I know that I am going to have to change them or up grade them.
1. Is a 302 head a swirlport type?
2. Would a 318 or a 360 magnum head be a better choice?
3. Should I put a set of 360 swirlport heads of this 318 and mill them and use a thiinner head gasket to off set the compression ratio lost with this swap? I am beyond confused. ANY SUGGESTIONS FOR YOU GUYS?
