I have an 87 305 bored out to a 355 was a tpi but is now a carb
it has the stock heads from the original motor but i am planning on changing those soon
any suggestions?
thanx

 

you can't bore a 305 out to a 355. the most you can get out of a 305 is 335 if you stroke it.

 

I am just going to guess that it is a 355 and the 305 was a mistype. I would say if you want them now and do not want to pay a ton of money then I would go for the Trickflow's. If you want to pay even less then that and do not mind Iron then the Dart Iron Eagle have been know to flow a lot.

 

Or if you want Alum. Then go with the Dart Pro 1s they are the same as the iron Eagles But alum.

I have the flow chart if you want it.

 

Vortec Heads

nice cam
650/750 carb.

400 H.P.

and thats the bottom line.
