Default need some fast help with heads

i found some lq9 317 heads on craigslist. low use titanium valves 2.00 int and 1.55 ex both 4.965 new manley titanium retainers nextek springs good for .650 lift. said 70cc chamber.


i have a ms3 cam and looking to put a decent set of heads on i have been looking at the patriot stage 2 and 3s but then i cam across these.

i have pacesetter headers

ls6 intake

will be buying ls6 oil pump and double roller.

i was reading somewhere my intake might not even fit on these heads is this true.

Thanks for all the help and taking the time to help me out thanks Ryan.

Your intake will work but with those big chambers compression will drop. I would look for a nice set of 243's....

The 317 heads will drop your compression so IMO they are not ideal for that size cam. Like previously stated, some 243 heads would be a little bit better of a way to go because of the smaller chambers they start with. Losing compression in the motor will make that cam lose low end power.

No you will need a stock 64cc chamber to clear that cam....or just a small cleanup mill....
