I have the d3ve a2a heads on my boat i just bought.My dad has a BBF that had the dove c heads and he put some procomps on it and gave me the dove c heads. How much better are they than my D3ve a2a heads and can i just put them on without having to change any of the valve train or pushrods? Compression difference? will i notice a power difference? Any input would be appreciated! Thanks, Blaine

The bad news: Your father's engine LOST power when he switched out the D0VE heads for the procomp heads (assuming no other engine changes). This is because the procomp head has a D3VE intake port, D3VE combustion chamber (20cc's bigger than the D0VEs and therefore he lost compression), downright lousy seat-to-bowl transition as delivered from procomp, etc. Basically, he lost power but saved 35 pounds (aluminum heads) which likely will not make up for the power he gave up. In the BBF world, the procomp heads are nicknamed "ProCrap" heads. (These observations may not apply if the engine is not stock and/or the heads were wildy reworked prior their to installation.)

The good news: You got yourself some D0VE heads! The D3VE heads utilize a different valve train than the D0VE heads, and so you will need to locate an OEM 1968-1971 429/460 valve train (very hard to find) or you will need to purchase a complete roller rocker valve train ($$$) and understand how to set it up correctly. When swapping out D3VE heads for D0VEs on a bone-stock 460, your compression ratio will increase from ~7.7:1 to ~9:1. Therefore, you will likely notice a power increase but the swap is not a simple "R & R" since you need different valve train, etc. Lot's to know and understand and a bit much for me to type at this time; grab a pen and paper and feel free to call and I'll be happy to point you in the right direction.

I am running Pro Comps on my 514 stroker and I have had no issues with them. I did have a buddy who works at a head shop here in town set them up for me. He did clean up the cc gasket matched everything valve job as they did not seat worth a flip out of the box, and they work great. The only thing i have been told about them is that you can not run a huge lift cam with high spring pressure as that is the weak point of them. The buddy who got them for me says they use them all the time and are running some big power motors and big turbo motors and no issues.

Thats what Russ the machinist told us about the springs and lift too. We had to buy $350 isky springs and didnt even run the pro-comps . The cam on this 460 has about .640 lift and Russ set us up with it and  got it all to to hold together for us. We have about an hour of firing time on the motor and no issues so far. Hopefully it stays that way! How much horse power is your stroker pushin? We are curious to see how much mph we gained. Its got a dominator pump in a 78 charger 19 3''. No pump work that we know of but is has the GS marine sticker on the pump so it could have something done. just a diverter.IT went 64mph with stock cam and dove c heads. hopefully we can hit 70!

Not real sure it is at the machine shop now. New cam Comp Hyrd (custom grind) roller new dual QFT 750's 4 tunnel ram and plate system install then onto the dyno. I am shooting for 700+ ish on motor around 900+ on the button. Going into my TX-19 light layup (300#) Berkley pump american turbine bowl droop diverter mpd prop and hopefully i can knock on triples door on motor and get 110 ish on the juice in 660'
