Thanks Mike! My heads should respond well to porting. I am sure you are right about the 4500rpm limit with unported heads. I will post flow data before and after porting, lets see what we can do.

Mike, You are correct about the 088 vs. 360. Almost anything is better than Peanut-Butter Heads.
Your expressed thoughts regarding advice are exactly as I was thinking I even went back and re-read post #1. It should be re written asking members for conformation of his plans.

Flow numbers and be darned, flow numbers never moved a boat post the dyno numbers.
This is where I say farewell and good-by to this thread.

Fat chicks, as you put it, tend to have strong oral fixation tendencies that can be quite nice! lol

you can lead a horse to water but you can not make it drink.if the op would listen he would realize that the 360 head won,t do what he wants.any shop worth a crap that has a flow bench already knows the 360,s limits.i will end by saying,good luck and enjoy your 375 hp engine,im out.

Default Heads and intake

I have a set of 088-head from my Mercruiser HP500 and also the Dart single plane intake. I live in Stockholm, Sweden so it’s not as far away from you. I could sell heads and intake to you for 800 euro + shipping. Send me an e-mail if you are interested [email protected], I could send you pictures and more info. Maybe I have the GIL exhaust manifolds to sell also
